Problems solved by technology
Since the welding is manually operated, it is very random and it is difficult to control the pressure
If the pressure of the electrode is too small, there will be poor contact between the electrode tip and the workpiece, causing arc explosion, burning the workpiece and damaging the electrode tip; there will also be false welding between the workpieces
If the pressure of the electrode is too high, the force on one side will cause a convex hull on the other side of the part, which will affect the appearance of the workpiece

Embodiment Construction
[0015] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0016] Such as figure 1 , figure 2 As shown, the rear portion of the welding torch housing 5 is a straight circular tube structure, and the front portion of the welding torch housing 5 has a horizontal positioning platform 5a, which is higher than the circular tube at the rear, and the rear of the positioning platform 5a The end is integrally connected with the top surface of the front end of the round pipe through an inclined section. Both sides of the rear part of the positioning platform 5a are provided with lifting ears 5b in a left-right symmetrical manner, and the upper ends of the lifting ears 5b are integrally connected with the corresponding sides of the positioning platform 5a. The electrode arm 1 is arranged below the positioning platform 5a, and the electrode arm 1 is a tubular structure. The front end of the electrode arm 1 exceeds the front e...

The invention discloses a single-faced welding gun. A positioning platform (5a) is arranged at the front part of a welding gun shell (5); a welding gun handle (6) is fixedly arranged on the top face of the positioning platform (5a); two sides of the rear part of the positioning platform (5a) are symmetrically provided with lifting lugs (5b); the lifting lugs (5b) are hinged with supporting lugs (1a) which are correspondingly arranged on an electrode arm (1); an adjusting bolt (8) is arranged in the middle of the positioning platform (5a) in a penetrating manner; the upper end of the adjusting bolt (8) is locked by a nut (9); a spring (10) is arranged below the adjusting bolt (8); the upper end of the spring (10) is abutted against a separation blade on the adjusting bolt (8); the lower end of the spring (10) is abutted against the top face of the electrode arm (1); and a micro-switch (4) is mounted on the bottom face of the front part of the positioning platform (5a). According to the single-faced welding gun disclosed by the invention, welding pressures are basically the same, so that the welding quality is guaranteed and the appearance effect of a work piece is prevented from being influenced.
Description
technical field [0001] The invention relates to a welding tool, in particular to a single-sided welding torch. Background technique [0002] Single-sided welding gun is an important tool for processing and manufacturing enterprises to perform single-sided welding operations. At present, a general-purpose single-sided welding torch is composed of an electrode head and a micro switch. The electrode head is connected to the main cable, and the electrode head is equipped with a micro switch for controlling welding. The micro switch is connected to the welding control line. When welding, the operator first needs to align the electrode tip to the welding position, then control the pressure between the electrode tip and the welding steel plate, and then press the micro switch to proceed. Because it is single-sided welding, only one side of the steel plate is stressed at the position of the solder joint, and the magnitude of the force directly affects the welding quality and appear...
