Development history of welder machine

In terms of the variety and technical characteristics of the welding equipment, in the early 1980s, most of the welding equipment produced in China was a relatively simple welding operation machine, roller frame, positioner, turning machine and rotary platform. The complete set was poor and the degree of automation was low. Can only be counted as mechanized welding equipment. In the late 1980s, the purchase of the space arm of the welding machine, due to the introduction of a large number of foreign advanced sets of welding equipment, promoted the technical progress of domestic welding equipment, whether it is the complete set of equipment, automation, equipment accuracy and manufacturing quality Different degrees of improvement.

At present, China has been able to produce 8m×10m heavy-duty column beam type operation machine, equipped with advanced narrow-gap submerged arc welding machine head gantry type longitudinal seam welder and column beam type narrow gap ring seam welder. The heavy-duty welding roller frame has a large tonnage of 400t. The heavy-duty container ring gap narrow-span submerged arc welding and the inner wall large-area surfacing must be equipped with the process equipment - automatic anti-smashing roller frame has been developed cmp champion international | entertainment and put into operation for many years, anti-smashing accuracy of ± 1.5mm. The welding positioner has been serially produced, with a large bearing capacity of 100t. Every year, various large and medium-sized single-side rotary and double-sided rotary turning machines for the welding of automobiles, locomotives and engineering machinery parts are put into operation. Large-scale production of automotive and motorcycle parts special arc welding machine and solder mask, large and medium-sized roll surfacing machine, large diameter pipe welding production line; H-beam and box beam welding production line. In the driving and control system of welding equipment, the more advanced AC motor frequency conversion speed regulation, DC motor thyristor speed regulation, PLC programmable controller, servo motor and its drive system, microcomputer and industrial computer control, etc. are widely used. . The degree of automation of welding equipment has been greatly improved. The welder manipulator can be equipped with an automatic seam tracking system and an industrial TV monitoring system according to the needs of the user.
