Longitudinal Seamers

The longitudinal seam welding system is used to weld inside and outside seams of medium wall thickness tank; It supports PAW, TIG and MIG/MAG welding process. The material processed can be carbon steel, stainless steel, aluminum alloy, titanium alloy and so on. It is widely applied in various applications of food machinery, dyeing and finishing equipment, power switch bus bar chamber, medical instrument, special material pressure vessel, electric power pipeline, air conditioner shell and so on. The fixture can be added with height blocks and protection devices.

>> Use copper-made finger clamp to achieve small welding distortion and high welding quality;
>> Suitable for welding longitudinal seams of 0.4mm-12mm wall thickness tank and plates.
>> Suitable for TIG, MIG/MAG, PAW PLASMA+TIG welding process.
>> Suitable for various materials, such as carbon steel, stainless steel, titanium alloy and aluminum alloy etc.
>>Optional to choose standard or cutomized mechanism according to work piece size.
