Description

Manual spot welding and continuous spot welding dual mode switching argon welder

This creation belongs to the field of argon welding machines, especially an argon welder that can switch between manual single-point welding, continuous welding or continuous spot welding, so that the argon welding torch head produces a single-point arc or continuous arc or intermittent arc. , welding workers with different requirements for working base materials.

According to the welding system, the welding rod is melted into solder by the high-temperature arc generated by the electrode, and the welding is performed on the working base material. In the conventional welding method, the welding place is easy to generate the surrounding air due to the local high temperature. Oxidation phenomenon; because the general electrode is coated with non-metal solder, it floats on the molten metal during the welding process to block the air from oxidizing the weld bead and the air, and some of the solder will be incorporated into the molten metal during welding. Impurities are formed to affect their mechanical properties. Therefore, in order to solve the oxidation phenomenon caused by contact with air during welding of the weld bead, an inert gas is used as a shielding gas to block the welding method of the weld bead and the air. Since the inert gas used is argon gas, it is called For argon welding (TIG), TIG is a non-consumable electrode welding method commonly used in stainless steel, aluminum and aluminum alloys (eg bicycles, etc.), copper and copper alloys, titanium and zirconium, low alloy steel and low Welding work between special steel and non-ferrous metals such as alloy steel pipes and various high-pressure pipelines. In the welding process, a tungsten rod is used as the welding electrode, and then argon gas is sprayed to cover the entire welding area, thereby preventing the welding electrode (cutting head) and the welding zone (cutting area) from being contaminated by air impurities during the welding process. In order to maintain the aesthetic and protective effect after welding.

At present, the existing argon welder uses the operation switch to switch the output of argon gas and the power supply of the welding electrode during the welding operation. Generally, the argon welder has two operation modes, single point welding and continuous welding type, single point welding type. That is, the operation mode of starting the protection gas and the electric power supply and output once every time the operation switch is pressed, and the continuous welding type is capable of continuously outputting the shielding gas and electric power after the operation switch is pressed. However, different metals have different melting points. When the heating temperature exceeds the melting point, the metal structure is decomposed and dissolved, causing problems such as excessive oxidation and carbonization.

In view of this, the creator deeply feels that when the operator uses argon welding to weld thin metal sheets, the weld bead is long, and if it is continuously welded, the working base material must withstand excessive heat and is easily deformed, if artificially Continuous spot welding by manual single-point welding is a physical test for the operator, and it is very difficult to control the welding quality, and the working speed is very slow and the efficiency is reduced.
