Compression roller and welding tip parallel with a distance of about 5mm. Bright-colored melting appears around welding tip. Solder skips, skip welding, scorch and infirm welding shall be forbidden.
3. At single-seam welding, the lap width shall be no less than 60mm for roofing project and no less than 100mm for underground project. As to double-seam welding, the reserved lap width depends on different welding machines.
