Types Of Welders Cheap Welding Supplies Best Portable Welder Welding Machine

Product Description

The portable spot welding machine uses the resistance heat generated by the current flowing through the weldment as a heat source for welding under pressure. Mainly used for spot welding of low-carbon steel parts of thin plate structures.

Portable spot welding machines are generally suspended in the air and connected to the welding tongs through flexible cables. The welding tongs of the portable spot welding machine have various structural forms to choose from, so the portable spot welding machine has a strong adaptability for large workpieces that are inconvenient to move, workpieces with complex shapes, or workpieces that must be stuck on the fixture for spot welding. In automobile body spot welding, the spot welding process for large sheet metal boxes has a wide range of applications and is an indispensable welding equipment.

♦ Distance,angle and length of welding arm can be made according to customers' requests.

Features:

1. The machine can rotate 360°as the turntable is configured with bearings.

2. Customized welding tongs, the longest welding arm is 1300mm and the shortest is 220mm.

3. The cylinder is a customized pressurized cylinder, the brand is (SMC).

4. During welding, the heating time is short, the heat is concentrated, and there is no electric arc, spark splash, welding slag, fusion welding accumulation, and thermal deformation of the weldment. In addition, after the innovation of the welding machine, the diameter of the gas path system is increased, so not only the welding productivity is high, but also the appearance of the weldment is beautiful and the quality is good.

Working Principle

The workpiece is pressurized and energized between the upper and lower electrodes, and having resistance welding.

When the resistance of the welding part is R (Ω), the welding current is I (A), and the power on time is t (sec), according to the formula: the current I that the metal material with a certain resistance value R passes through within a certain time t heats up due to the resistance, and the heat generated is Q. The metal resistance current is used to heat the molten metal, and then the metal is cooled, crystallized and connected under pressure. This is called resistance welding.

Welding Arm Can Be Customized

Overview of product structure

This series of welding machine is mainly composed of welding transformer, gas circuit (pressurization) system, water circuit (cooling) system, welding tongs, resistance welding controller and motion mechanism. According to the shape of the workpiece to be welded and the operating conditions of the welding machine, the welding tongs have a variety of structural forms.

X type welding machine is suitable for welding on horizontal plane or near horizontal plane, and C type welding machine is suitable for welding on vertical plane or near vertical plane. The shape of welding tongs can be designed according to user requirements.
