Submerged arc welding

Section submerged arc welding Submerged arc welding is a solder layer in particulate combustion automatic arc welding, welding can be divided into two kinds of automatic and semi-automatic, semi-automatic submerged arc welding equipment, but no one is too cumbersome to use, were switched CO: GMAW or SMAW. First, submerged arc welding submerged arc welding processes and characteristics 1. submerged arc welding process welding Welding is white is the use of special equipment for welding submerged arc welding, the welding had shown in Figure 3-1. Z after the end of the wire is generated between 7 and weldments Arc 2 around the ends of the wire arc thermal defend molten solder 5 has partially evaporated vapor flux arc melting solder week - slag 4 line, and form a closed space, the arc and the outside air, the arc in this space continues to burn, the wire will continue to melt down, and the weldment is melted liquid metal were mixed to form a weld pool, the arc is moved forward, also will be cooling the molten weld pool solidification, and droplets with the welding, weld forming less dense slag floats in the surface of the bath, cooled to a crusts So the welding official website http://www.cslds.com/html/product/ http://www.cslds.com/html/product/38.html http://www.cslds.com/html/product/40.html http://www.cslds.com/html/case/ http: //www.cslds.com/html/lianxi/18.html Sales Hotline: 13,307,488,120 15,111,262,125 Wang Zhang business QQ: 2027188073 Tel: 0731-89921482 Sale: 18974874048
