Fused surface defects include cold welding and fusion surfaces Such as the inclusion of such defects are area-type defects. 3.4 Cold welding coldwelding Due to the lack of welding input heat makes the fusible link in the pipe and pipe interface on the molecules failed to spread tangled or fully diffuse tangled Resulting in deficiencies of insufficient strength. 3.5 Fusion surface After welding residue in the fusion interface on the oil, dust and other debris. 3.6 Hole hole In the welding interface or near the welding interface of the hole. This type of defect is a volume defect. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 29460-2012_English be delivered?Answer: Upon your order, we will start to translate GB/T 29460-2012_English as soon as possible, and keep you informed of the progress.
