The blanking of thin-walled pipes can be processed by sawing. Since the sawing incision is very narrow (compared to the grinding wheel, it reduces material loss by 60%), and it can be automatically sawed in bundles, so sawing is used. The processing method is an economical and high-efficiency ...... [Read More]

When using a band saw to cut H steel, I-beam, angle steel and channel steel, make sure not to cut obliquely. Once the material is cut obliquely or cored, it will affect the subsequent material welding process and cause the welder to polish the excess material. Or adding filler materials, or wo......
