Unit for longitudinal welding of sheets and shells by TIG/plasma
Country: · Model: Longitudinal seam welding unit
The unit automatically welds straight longitudinal butt joints of sheets and cylindrical shells with a non-consumable electrode or plasma. The edges are brought together butt to butt without bevelling and without a gap, so the method suits thin-walled products made of stainless steels and alloys. It is used in chemical and food machinery, power engineering and heat exchanger production.
- Purpose

Description
The clamping system aligns and positions both edges end to end, after which the torch moves along the seam at a set speed. According to the manufacturer, such units use TIG and above all plasma welding, which penetrates the joint through the full thickness in one pass. Torch movement, filler wire feed if it is needed, arc voltage control and shielding gas are handled by a PC series power source with a built-in multi-axis controller. The PC 600-3 source supports TIG and plasma with cold or hot wire up to 550 A. Typical products are vessel shells and pipes rolled from sheet.
How to choose
The size of sheets and shells depends on the unit version, and the sources give no specific dimensions, so they are agreed for the product. Thin joints with penetration in one pass are more convenient to weld with plasma, while TIG remains for cases where filler is needed. If circumferential pipe welds must be made, look to orbital heads, for example MU IV with a range of 8–195 mm.

FAQ
Which welds can be made on this unit?
Straight butt longitudinal welds of sheets and cylindrical shells without edge preparation and without a gap.
Why is plasma better than TIG for longitudinal joints?
According to the manufacturer, plasma penetrates the joint through the full thickness in one pass. TIG is used where filler wire is needed.
Which power source controls the unit?
A PC series power source with a built-in multi-axis controller. The PC 600-3 model provides TIG and plasma up to 550 A with cold or hot wire.
Which materials is the unit intended for?
For thin-walled products made of stainless steels and alloys.
