China Suppliers Factory DC IGBT 150AMP Portable ARC/MMA 200A Inverter Welding Machine for Household Use
Detailed Information
Manual welding is easy to operate, flexible to use and strong in adaptability. No auxiliary gas protection is required, and it has strong wind resistance. It is suitable for welding of various steel types, various angles, various positions and various structures. Especially for irregular welding seams, short welding seams, upward welding seams, high altitude and narrow welding seams, it can be flexibly used and operated freely.
The welding quality is good. Due to high arc temperature, fast welding speed and small heat-affected zone, the mechanical properties of welded joints are ideal. In addition, due to the continuous improvement of welding rods and electric welding machines, in the welding structure of commonly used low-carbon steel and low-alloy steel, the mechanical properties of the weld can be effectively controlled to meet the requirements of the same strength as the base metal. For weld defects, within a certain range, it can be overcome by improving the level of welders and improving technological measures.
Manual arc welding is easy to disperse stress and control deformation. In all welding structures, due to the action of thermal stress, there are welding residual stresses and deformations. For welds with complex shapes, long welds and welds on large workpieces, the problem of total residual stress and deformation is more prominent. Manual arc welding can be used to reduce deformation and improve stress distribution through process adjustments, such as skip welding, reverse segment welding, and symmetrical welding.
The equipment is simple and easy to use and maintain. Regardless of the AC welding machine or the DC welding machine, welders are easy to master, reliable to use, and easy to maintain. It is not as complicated as submerged arc welding and electroslag welding equipment.
