Abstract

This present invention discloses an arc stud welding machine, comprising a welding device, a controller, a welding power supply, a ground clamp connected to welded workpiece and a welding cable. The present invention is characterized in that the welding power supply is direct current supply of instant output maximum current with declined and static characteristics, which also comprises a welding fluid box and a conveying and recovery mechanism of welding fluid. The welding fluid conveying and recovery mechanism is provided with a conveying pipe and a recovery pipe of welding. The conveying pipe and the recovery pipe are respectively connected with the welding fluid box. The welding fluid box is installed in the welded device and positioned in the contacting point of a weldment and a welder. An operation method of a hidden arc stud welding machine is: the power supply is switched on, the welder is held on, and welding, cooling and slag clearing are practiced. The hidden arc stud welding machine has features of effective protection for a molten pool and a welding line, sufficient reflection for metallurgy, large penetration, and a high-strength welding line. The welder is inserted into the molten pool and the welding joint is firm. The high-ridged welding line enhances mechanical strength of the welding joint.

Description

technical field

[0001] The invention relates to the technical field of stud welding, in particular to a submerged arc stud welding machine and an operating method thereof. Background technique

[0002] Submerged arc stud welding is mainly used in the welding of "rebar T-welding" embedded parts of large steel structure buildings. The traditional welding method of reinforced T-welding embedded parts is "manual welding" or "perforated plug welding". The main disadvantages of these two welding methods are complicated procedures, slow welding speed and low efficiency. Arc stud welding is a full-section welding method with simple operation, fast speed and high welding quality, so it is rapidly promoted in steel structure buildings. However, when it is applied to the welding of "reinforced T-welding" embedded parts, a large number of pores will appear in the weld, accompanied by impurities and cracks, thus greatly reducing the mechanical strength of the weld. The main reason is ...
