1) Longitudinal Seam Welding Machine, as its name suggests, is used for implementing whole length longitudinal seam welding on thin wall cylinder bodies, in the materials of stainless steel, Al, alloy, carbon steel, etc. The thickness of workpiece for this Welding Equipment ranges in the scope of 1mm~ 5mm;
2) The welding mode in Longitudinal Seam Welding Machine is majority TIG, which has high precision and fine welding seam formed.
1) As can be seen from the lefthand photos, the Longitudinal Seam Welding Machine is in the structure of fixed working table;
2) There is a piece of horizontal gloss solid mandrel beneath working table of the Welding Equipment, which comes all the way through internal of the cylinder, serving as workpiece fixture during running of the Longitudinal Seam Welding Machine;
3) Right above the cylinder, there is an array of keys, which are driven with and clamped by means of air cylinder, for fixing the cylinder firmly, in the period of Longitudinal Seam Welding Machine operation;
4) During work, the welding head move along working table of the Longitudinal Seam Welding Machine, in the adjustable working speed of TIG welding;
5) During working of the Welding Equipment, the mandrel is circulated with cooling water, guaranteeing non-deformation of the thin wall workpiece, which is being welded in this Longitudinal Seam Welding Machine.

Roller Strap Cladding Machine, the other names are Built-up Welding Machine, or Hardfacing Welding Machine, is for depositing a layer of hardfacing on surface of workpiece, especially cylinder bodies, to prevent the workpieces from growing worn.
1) The welding mode in this Welding Equipment of Roller Strap Cladding Machine usually adopts with SAW, which should feature in small welding current and large welding voltage, rendering thin layer of hardfacing formed on external face of cylinder body;
2) During working of the Roller Strap Cladding Machine, the workpiece is support on a set of Welding Rotator, which revolves the workpiece into rotation, the corresponding linear speed should be adjusted by means of inverter;
3) Meanwhile, welding head moves along transverse beam of the Welding Equipment, making welding performed in the constant pitch, attaining the purpose of hardfacing in this Roller Strap Cladding Machine.
