Abstract

The invention relates to a welder, in particular to an automatic butt welder, which is applicable to welding between cylinders with different diameters and tube plates. The automatic butt welder comprises a straight shank empty cold welding torch, an elevating gear and a transversal arm fixed on the elevating gear, wherein the straight shank empty cold welding torch is fixed on the transversal arm. The automatic butt welder is characterized in that the transversal arm is formed from a front arm and a rear arm connected by a coupling, springs are fixed on the front arm and the rear arm, a sleeve with adjustable height is arranged on the front arm, a transversal sliding shaft is arranged on the lower part of the sleeve, a roller is arranged on the top end of the transversal sliding shaft, a longitudinal telescopic rod is arranged on the front arm, a curved rod is arranged on the top end of the telescopic rod, and rollers are arranged on both ends of the curved rod. The automatic butt welder has a unique mechanical limit structure of the front arm and the rear arm, solves the problem that the head of a welder is regulated continuously during welding because a cylinder rotating on a rotator deviates longitudinally, and ensures no deviation from welds during welding.

Description

technical field [0001] The invention relates to a welding machine, in particular to an automatic butt seam welding machine, which is suitable for connecting and welding various diameters of cylinders and tube sheets. Background technique [0002] Existing evaporators, condensers, and tube-to-sheet joints are all welded by manual gas shielded welding without exception. As a result, workers have poor working conditions and high labor intensity. Due to differences in the technical level of welders, welding quality problems will inevitably occur. The most difficult thing to control in gas shielded welding is the gas shielding of the welding bath. Due to the manual welding of workers, it is inevitable that fatigue will occur during the welding process, and the technical level will not be correct, which will inevitably lead to the deviation of the angle of the welding torch nozzle and the extension length of the welding wire is too long or too short. The result is: the nozzle is ...
