Our company operates a DC welding machine MTV 8002-2 from the beginning of 2009.The machine is manufactured according to our technical specification at the enterprise «Technosvar KS» Ltd., Pskov. MTV 8002 - 2 has an increased solution of 1200 mm (standard version 600 mm), for welding large-sized products. In addition, according to our order, the machine was equipped with an autonomous cooling system and a compressor. The machine is used for resistance spot welding of structures from aluminium alloys AMg2, AMgZ, AMg5, AMg6 with a thickness of 1.0 to 4.0 mm.
During the operation the machine proved itself on the positive side. Thanks to the functions of tolerance control, visualization of the welding process, the process of equipment adjustment and selection of process parameters was simplified. Thanks to the certification of the welding joint, it is always possible to get an answer on what parameter the defect occurred.
After the introduction of the equipment mentioned above, the quality of work performed by spot welding of critical structures has increased significantly, unproductive losses have decreased, and the period of preparatory and adjustment work has decreased.
Yours faithfully,
First Deputy General Director- Chief Engineer
