welding seam tracking solutions

Selecting the Right Seam Tracking Solution

In today’s highly competitive market, manufacturers must stay both lean and efficient. Taking advantage of the different seam tracking options available for your welding projects is one way to gain an edge.

Here at Bancroft Engineering, we understand the importance of optimizing your welding process.

Tactile Seam Tracking

Tactile seam tracking systems track the seam using a sensor with a tip that physically touches along the length of the seam about 2-3” in front of the arc. When a change in location or alignment is detected, the system responds and adjusts to the correct position. It can be used in almost any welding process.  Tactile seam tracking is very versatile and works well on any material type. This option offers a great balance between cost and flexibility.

One disadvantage to tactile seam tracking is that the torch is adjusting in real time according to where the probe is touching not where the torch is welding.  If the probe is 3” in front of the arc and a quick drastic change to the seam is detected the arc may actually move outside of the seam. To solve this problem the tracker can be paired with another type of control system to delay the correction in relation to the travel speed of the weld head or part.

Through Arc Seam Tracking

Through arc seam tracking is a type of 2-axis real-time tracking.  The tracking occurs as the weld is being deposited and adjusts by monitoring the voltage across the arc.  In order to shift along 2 axes’ with through arc tracking weaving is required.  As the tip to work distance changes so does the voltage across the arc.  This change in voltage is monitored and used to adjust the path of the torch, maintaining proper weld position in the joint.

Laser Vision Seam Tracking

Laser based vision tracking, also referred to as optical tracking, involves a laser beam device which hits the welding surface, reflects off and bounces back to the sensor. With this technology, the sensor then recognizes exactly where the seam is located. Laser vision seam tracking is highly reliable and great for high speed welding applications for both small and large parts.

Touch Sensing

Touch sensing, or wire touch sensing, is the physical touching of the weld wire to the welding surface to detect the joint. Most commonly used in robotic welding applications, this type of seam tracking uses low voltage through the welding wire or torch tip to search and detect the welding surface and seam.  The seam needs to be detected prior to welding so the cycle time can be double or more compared to that of other methods.

Semi-Automatic Welding Machine

Semi-Automatic Welding Machine –The Best Choice

 Ready to optimize your manual welding process to a more efficient operation and consistently improve your end products? Updating your welding methods with a semi-automatic welding machine will take your manufacturing process to the next level—all while increasing your profit margin.

Robotic or fully automated welding is not ideal for every project—expected lifetime of the job, the cost of tooling and the flexibility required are all factors that should be considered. That being said, semi-automated welding systems are a great option because they can double the output of a skilled manual welder while still maintaining a high level of control.

  

What is Semi-Automatic Welding?

Semi-automatic welding is a form of manual welding that utilizes the proper equipment which automatically controls one or more of the welding conditions. The machine operator manipulates the controls of the machine to start welding and observes the process and end result for quality. This is helpful to workers as it’s much less physical demanding than manual welding.

 

Advantages of Semi-Automated Welding Machines

Applications that benefit most from semi-automated equipment is when the quality or function of your weld is highly critical, if repetitive welds must be made, or if the parts already have gone through added-value processes before the welding begins. Semi-automatic welding systems offers a host of advantages for a variety of applications:

  • Enhances worker safety
  • Maintains high-quality welding output—integrity and repeatability
  • Increases overall product output
  • Decreased scrap produced
  • Less expensive than robotic welding

Section 179 Expensing for Welding Machines in 2019

With the new year right around the corner, it’s a great time to plan for tax savings before it’s too late. Purchase automated welding machines from Bancroft Engineering to not only improve your manufacturing process but also to save your business money during tax time.

 

How Does Section 179 Expensing Work for Welding Equipment Purchases?

Section 179 of the United States Internal Revenue Code (26 U.S.C. § 179) is now available which allows you to write-off up to $1,000,000 of a qualifying equipment purchase for 2019.

In previous years, when businesses purchased welding equipment, they would write it off little by little through depreciation. For example, if your business spends $75,000 on a piece of machinery, you might write off $15,000 per year for five years.

Now, with Section 179, a business can write-off the entire purchase price of qualifying equipment for the current tax year. As in our previous example, if your manufacturing business spends $75,000 on a piece of automated welding machinery, you can write off all $75,000 in the same tax year using Section 179. This makes a big difference for small and medium-sized businesses as it allows you to accelerate your tax savings!

How to Qualify for Section 179

Section 179 is an attractive tax deduction for manufacturing businesses—it’s also easy to understand and utilize. Most new and used tangible business equipment qualifies as long as it meets the following criteria:

  • Equipment must be installed and ready for service in the same tax year
  • More than 50% of the use of the equipment must be used for the business

 

Real Example of Section 179 Expensing

  • Cost of equipment after Bancroft Engineering Discounts: $175,000.00
  • Section 179 Deduction: $175,000.00
  • Total First Year Deduction: $175,000.00
  • 35% Saving on Equipment Purchase: $61,250.00
  • Lowered Cost of Equipment After Tax Savings: $113,750.00

Tips to Prepare Metal Before Automatic Welding

Understanding the importance of clean metal before you begin any automatic welding, semi-automatic welding or manual process is key to a strong end result. Skipping the metal preparation step is one of the most overlooked tasks in the welding process, but it shouldn’t be! You run the risk of failing quality inspections or end up with ugly—or even weak welds.

Material preparation will vary depending on what type of tools you have such as automatic welding equipment, rotary welding systems, TIG welding cells or if you are welding manually. It will also depend on what type of metals you are using. Read on to get our general best-practice tips on how to prepare metal before welding.

 

Keep it Clean

Beginning with clean, debris-free material is the best way to ensure positive outcomes. Before using an automated welding system, remove any paint, oils, grease or rust. Here are a few common tools used to clean metal:

  • Sandpaper
  • Abrasive blasting
  • Stainless steel brushes
  • Solvents such as acetone or other alkaline cleaners

Avoid creating any deep scratches when cleaning your material as removing too much material from the metal can result in poor weld quality and costly rework. Always organize your cleaning utensils and keep ferrous and nonferrous tools separate. Cross-contamination can occur when the wrong cleaning tool is used.

 

Removing Oxide Layers

If you’re welding with aluminum, it can add an extra element of difficulty due to the nature of the metal.  Aluminum has a greater risk to develop weld problems— such as lack of penetration—due to the tough oxide layer. Other metal materials may also have a coating on them to avoid rust during shipping. Oxidation can from quickly, so it’s best to clean small areas at a time right before the automatic welding process begins.

Joint Preparation

Preparing the metal’s edge is a critical step that allows the filler metal and part edge to fuse together without melting. Depending on your parts, one of these basic weld joints should be used:

automatic welding equipment
  1. Butt joint: parts are on the same plane and they are joined at their edges.
  2. Corner joint: parts form a right angle and are joined at the corner of the angle.
  3. Tee joint: one joint is at a right angle, while the other resembled the letter “T.”
  4. Lap joint: formed with two overlapping parts.
  5. Edge joint: joints are parallel with each other and are joined at the seam.

 

Proper Storage

A major challenge is preventing indirect material contamination from dust or other airborne particles floating through your shop floor.  While you can’t stop dust and dirt completely, here are a few material storage tips to keep in mind:

  • Store in a dry location
  • Ensure minimum temperature fluctuation
  • Cover materials with plastic or thin sheets of cardboard

 

Automatic Welding Systems

No matter what type of welding you are performing, it’s important to take the time to prepare your material before you get started. It’s worth the extra effort to get a strong weld that also looks perfect!
