Longitudinal Seam Welders

Jetline seam welders, also known as stake bed welders, horn welders, and flat sheet welder are designed for all straight line, linear welding applications. They can be used to weld tubes, cylinders, cones, flat sheets, sinks, tank shells, and open ended boxes. The following materials can be welded in a Jetline seam welder: aluminum, stainless steel, hastelloy, titanium, inconel, galvanized, aluminized, and other materials.  Any model can be engineered to automate your application. Jetline specializes in providing a customer driven solution to your automated welding needs.

 

Jetline seam welders include the following features:

  • Shallow clamping structure design (enhances visibility).

  • Reversible, copper finger tips.

  • Adjustable mandrel for optimum material thickness adjustment.

  • Toe touch clamping strips (operable from any point along the  weld seamer length).

  • Stress relieved track with casehardened travel carriage ways.

  • Jetline seamwelders can be supplied with TIG (gas tungsten arc welding), MIG (gas metal arc welding), PAW (plasma arc welding), or SAW (submerged arc welding)

Precision is the hallmark of every Jetline seam welder. Special gages ensure the alignment of the weld joint. Custom designed chill bars control penetration and minimize distortion. As the welding head/carriage moves accurately along the seam, quenching or cooling is uniform along the joint. Consistent travel speed provides further assurance of an accurate, high quality butt weld with 100%(percent) penetration.

 

Jetline manufactures variety of seam welders including the following types:

External weld seamer is used where it is desired to weld from the outside of the vessel with the penetration bead on the inside.
 
Internal seamers are designed for the welding of flat sheets and large diameter cylinders. They are manufactured in standard lengths up to 300" (7,600 mm) and can be manufactured in longer lengths as a special product.
 
Combination seam welder is designed to weld externally up to a diameter of about 52" (1,322 mm) and then weld internally above this diameter. This provides a much larger diameter range.
 
Elevating seamers weld the part externally. The whole tabletop and mandrel assembly is hydraulically lifted and lowered to accommodate different part diameters.
 
Bench Style seamwelder is manufactured for the welding of small parts with weld lengths up to 36" (915 mm).
 
Jetline Seamers are available in lengths up to 240" (6,100 mm) and longer, in three different types; standard, precision and ultra precision.
 
Standard models feature a linear tracking accuracy of ±0.015" (0.4 mm) and utilize a rack and pinion drive for the travel carriage.

Precision models are built to provide a tracking accuracy of ±0.005" (0.1 mm) with a rack and pinion drive carriage. They include continuous clamping strips for the precision welding of thin material.

Ultra Precision models include all the features of the precision types but use a linear drive carriage to provide backlash free, ultra smooth movement of the welding equipment along the weld joint.
 

A Jetline Seamer used in conjunction with our wide range of controls, accessories, and system integration capabilities the seam welder becomes a fully integrated welding system for any type of application.
