Welding Seam Tracker – The Comprehensive FAQ Guide

Should you be trying to find out what welding seam trackers are, you’re just in the right page! Today, we’re going to discuss everything you need to know about welding seam tracking systems.

As a bonus part of this guide, we’ll also help you find the best welding seam tracker manufacturing company to help you with your needs!

What is a Welding Seam Tracker?

Welding seam trackers are the machines or the equipment to have a weld seam tracking system.

It utilizes real-time tracking advanced than where the weld is deposited.

You’ll want to use welding seam trackers so that the controls and adjustments modify themselves accordingly, too.

The usage or the utility of sensors in robotic welding can absolutely replace manual welding. This enables welding procedures and processes to be applicable in high temperature, high impact, as well as complex and dangerous environments.

What is a Welding Seam Tracking System?

A welding seam tracker system is a type of system that uses automation for the benefit of the welder.

With a welding seam tracker system, the sensors of your welding heads would be automatic. They’d know specifically the distance between the sensor and the laser emitter.

Is it Possible to Use Seam Tracking Systems For Laser Welding?

Yes, there’s no written rule that you can’t use a welding seam tracker for laser welding.

is it possible to use seam tracking systems for laser welding What laser welding looks like

However, there have been reports of it being inaccurate because of the position of the laser weld. Therefore, the best approach to this is to ensure that the laser welding head is positioned and is placed accurately and precisely.

Types of Welding Seam Tracker Systems

Contrary to popular belief, there are a few different types and kinds of weld seam tracking systems.

types of welding seam tracker systems Laser vision seam tracking – one type of welding seam tracker system

They include, but are not limited to:

Laser Vision Seam Tracking

This particular type of welding seam tracking systems use lasers that project to the surface of the material’s part. You’ll be able to view it using a camera at a specific angle.

Then, the result will be in a line profile that’s identical to the weld seam geometry or specific measurements.

Tactile Seam Tracking

From the term alone, you’d already know that it utilizes tactile or physical sensors. These are the things that “touch” the seam using a probe.

When the position of the torch moves, the contact probe sides in the opposite direction. The controller will also make adjustments to revert it to its original position.

You’ll want to use tactile seam tracking for specific or distinct geometry, large weld seams, etc.  

Through Arc Seam Tracking  

The through arc seam tracking, or the TAST type of welding seam tracker utilizes feedback from the combination of wire feed speed sensors, voltage, and amperage sensors for the modification of the position of the torch.

Akin to tactile seam tracking, you can use through arc seam tracking for large weld seams or welds that need accurate and precise welding.

What is Laser Seam Tracking?

It’s one of the classifications of seam tracking where the laser beam is what you use for the welding procedure.

What it does is it shoots a beam and hits a surface, then, reflecting off of the surface, which then bounces back and gives the signal to the sensor.

This is when the sensor picks up all the information needed for the modifications and the adjustments to be made.

What is Long Seam Welding?

Long seam welding, or more commonly referred to as longitudinal seam weld or continuous weld, is a procedure that discusses the resistance over longer periods of time.

It’s the complete opposite of what an intermittent welding is; which is the type of weld where it isn’t continuous.

What is Seam Welding Used For?

Since seam welding is the procedure of fusing two (2) types of different materials together, you can use seam welding for a ton of different applications.

However, you can utilize seam welding to process metals because they’re able to conduct electricity easier, better, and more effectively. In addition to that, metals are also capable of sustaining high pressures and impacts compared to regular steels.

Apart from that, though, you can use seam welding to create fluid-tight and gas-tight joints such as in radiators, tin cans, steel drums, tank and pressure vessels, motor vehicles, and many more!

Which Type of Electrode is Used in Laser Beam Welding?

The electrodes that you want to use in laser beam welding would be those that have thin materials that contain millisecond-long pulses.

You need to make sure that the electrodes you’ll be utilizing is fit for the laser beam welding procedure.

Which Welding Seam Tracker Supplier Should You Trust?

In the market, there would never be a shortage of welding seam tracker suppliers.
