Here is Why Linear Seam Welding is Most Important Equipment in Welding Industry

Workshops across various industries trying to produce linear welds confide in linear seam welders. As the name suggests, they create a linear weld across the longitudinal seam of a tubular pipe, or flat plates etc.  Specifically, it is useful for many applications where the edges of the material need to produce a rigid structure after transforming them into the desired shape like a cylinder, rectangular tube etc. 

How it works?

Considered as one of the most effective equipment in welding industry, linear seam welders use pneumatically controlled chrome plated copper clamps to contain thick material of up to three-fourth inch (3/4"). The welding carriage then produces a high quality and consistent weld. The equipment produces linear welds in a range of process including MIG, TIG, Plasma and Submerged Arc. All these processes accompany water-cooled back-up bars with or without gas purge.

How it differs from traditional methods?

Traditionally, linear welding is carried out in different stages, such as the edges of the material are held in alignment, followed by tack welding and then linear welding. This is performed using a simple carriage consisting of the welding torch. However, this process is time-consuming and costlier owing to various factors:

• It is hard to hold the edges accurately in alignment for the complete stretch of the part.
• Equally difficult is to maintain the part’s dimensional accuracy.
• Tack welding consumes considerable time and often causes defects in the tack weld area.
• The less sensitive chilling of weld joint areas could oxidize and distort the surround and weld area.

Seam Welders – Suitable alternative

Linear seam welders provide a befitting solution to all these shortcomings as they have a specific design for the straight line welding in varied thickness of the materials to be weld. In addition, they:

• Minimize cost of welding
• Optimize the welding process
• Improve welding quality

Custom Models

Several manufacturers hold expertise in coming up with custom models based on the requisite functionality and capacity. These include the range of diameter, welded material type, seam length, material thickness (min. and max,) followed by the ideal welding process. Red-d-arc is the best company to consider in this regard, as it holds credible experience in the manufacturing of quality seam welders along with other related equipment.
