The solid state high frequency welder is installed between the forming machine and the sizing machine. And it can rapidly heat and weld two edges of tube blank after steel strip is rolled into circular tube blank with an opening seam. Then squeezing rollers help form sealed tube. As the critical equipment of tube forming, it directly determines welding quality, production speed and operating cost of the whole production line.
1. High welding efficiency: Its welding speed far exceeds that of gas-shielded welding and argon arc welding. That can match high-speed tube mill line and is suitable for large-scale continuous production.
2. Excellent welding quality: Its heating area is very small with less tube deformation and smooth surface. And oxides and impurities can be expelled in squeezing. So, welding seam is dense and narrow. Besides, tube still keeps original strength.
3. Low operating cost: It only needs electricity and cooling water instead of welding wire and shielding gas. Also, the machine can lower energy consumption and maintenance cost.
4. Strong automation compatibility: It can be integrated with tube mill, accumulator and cold saw, etc. And it can automatically adjust welding power based on production speed. That can guarantee fully automatic and continuous production.
