Discussion on welding method and steps of pp plate

Speaking of PP board, I believe many people will feel strange. Indeed, in daily life, people rarely see PP boards. But in all kinds of industrial equipment, PP board is a widely used material, such as the first choice of stamping board for all kinds of industrial equipment, such as solar photovoltaic equipment, environmental protection equipment, plating equipment, waste water and waste gas discharge equipment, the backing plate of punching machine, etc. The following small series will briefly introduce the PP board for friends.

What is a PP board?

PP board is a semi-crystalline material. Compared with PE board, PP board is harder and has higher melting point. In general, in order to improve some properties of pp sheet, a certain amount of materials such as ethylene copolymer, glass fiber, metal additives or thermoplastic rubber will be added to PP sheet.

What are the welding methods and steps of pp board?

Pp sheet is one of the most environmentally friendly materials, which is non-toxic and tasteless, and has excellent chemical resistance, heat resistance and impact resistance. It is worth mentioning that the biggest feature of pp sheet is its low density and easy welding processing. At present, most pp plates are welded by hot gas welding process, and the main welding steps are as follows:

First, the preparatory work.

"If the people want to benefit their affairs, they must first sharpen their tools." To do a good job of welding pp board, we must first do a good job of preparation. First of all, welders need to wear work clothes, and those with long hair need to wear working hats. In addition, before the welding work begins, carefully check whether the welding torch is normal, especially whether the screws of the nozzle and gun body of the welding torch are loose or fall off. Finally, connect the power cord of the welding equipment to ensure that the power supply is not loose.

Second, the pre-welding treatment of pp board.

Before welding, it is necessary to wipe the pp board clean to ensure that the welded part of the pp board is dry and free of dust and grease. In addition, it is necessary to chamfer the edge of pp board.

Third, the welding of pp board.

At the beginning of welding, it is necessary to clamp two pp plates with clamps to ensure the correct welding position of the pp plates. When welding, the welder needs to hold the welding workpiece with one hand and hold the covered electrode in the welding area with the other hand. It has to be said that the welding quality of pp plate depends on the welding pressure control by the welder.

Fourth, after welding work.

After welding the pp board, it is necessary to put the welding torch on the workbench first, then cut off the power supply, clean up the work site, and finally put away the welding tools and materials and put them back in their original places.

The above is Bian Xiao's introduction to the welding methods and steps of pp board, hoping to help friends in the welding process of pp board.
