查询词典 arc welding

This article has mainly studied one kind improved two person two-sided synchronized GTAW craft for the austenite stainless steel. This craft makes the improvement in the original two person two-sided synchronized GTAW craft foundation which one time welding two-sides formings. A series of welding engineer testing on 8 mm SUS304 were carried on. The new craft could guarantee the welding quality in contrast with the original two person two-sided synchronized GTAW.

主要研究了一种改进了的奥氏体不锈钢的双人双面同步钨极氩弧焊工艺，此工艺是在原有的双人双面同步钨极氩弧焊工艺的基础上进行的改进，即将原有的一次焊双面成形改为两次焊成型，并在厚度为8 mm SUS304上进行了一系列焊接工艺试验，验证了这项新工艺与常规双人TIG双面焊相比，能保证焊接质量。

PP-H welding method is commonly used in thermal contact welding and the use of hot gas welding electrode.

Renqiu City, Hebei Province, Richwood Welding Equipment Co., Ltd.(formerly Renqiu City Huifeng Welding Equipment Factory) is located atthe original scenery of the banks of Baiyangdian, my company was founded in 1975, are the production of CO2 gas shielded welder , the professional manufacturer of welding torch.

河北省任丘市嘉丰焊接设备有限公司（原任丘市惠丰焊接设备厂）座落在冀中平原，风景秀丽的白洋淀之畔，我公司始建于1975年，是生产CO2气体保护焊机、焊枪的专业厂家。

Department can not repair welding welding Welding and machining should be cleared of the original; 3, remove the screw, loop cleaning, replacement of defective parts, ground sealing and connecting seat seal surface, re-assembly.

五、关闭件脱落产生泄漏：原因： 1、操作不良，使关闭件卡死或超过上死点，连接处损坏断裂； 2、关闭件连接不牢固，松劲而脱落； 3、选用连接件材质不对，经不起介质的腐蚀和机械的磨损。

Mechanical properties and hardness of the welding joint was tested, and microstructure of welding wire and welding joint were observed via OM, XRD, TEM and SEM. Analysis and explanation in theory were also given.

测试了焊接接头的拉伸力学性能和硬度分布规律，采用金相显微镜、X射线物相分析、透射电子显微镜和扫描电子显微镜观察了焊丝合金和焊接接头不同区域的显微组织结构，并从理论上进行了分析和解释。

The results show that, the coefficients of welded joints are both greater than 0.9, but the yield strength of weld joint filled with Al-Mg-Zr-Sc welding wire is greater 100 MPa than that of filled with Al-Mg-Zr welding wire. It indicates that the Al-Mg-Zr-Sc welding wire is the best alteration of filling materials to weld of Al-Mg-Sc alloy.

但采用Al-Mg-Zr-Sc合金焊丝为填充材料时，焊缝晶粒组织明显细化，熔合区形成的细小等轴晶层提高了基材与焊缝填充材料的结合力，焊接接头的屈服强度比采用Al-Mg-Zr合金焊丝为填充材料时提高了100 MPa，显著提高了Al-Mg-Sc合金焊接构件的许用强度，因此焊接Al-Mg-Sc板材更宜采用Al-Mg-Sc-Zr焊丝。

The invention relates to a method for preventing a top metal layer of packaging chips from fracturing under high temperature, which avoids the fracture of the top metal layer caused by the inter-diffusion of a gold ball, an aluminum welding pad and a top layer metal by introducing a lower metal layer to the joint between the top layer wire and the aluminum welding pad and driving a metal plug to the joint between the top metal layer and the lower metal layer and a metal plug to the joint between the lower metal layer and the aluminum welding pad.

一种防止封装芯片上的顶层金属层在高温下断裂的方法，通过在顶层金属线和铝焊垫之间连接处引入下层金属层，并在顶层金属层和下层金属层之间的连接处以及下层金属层和铝焊垫之间的连接处打金属插塞，避免了因金球、铝焊垫以及顶层金属相互扩散造成的顶层金属层断裂。
