Get Precise Welds on Critical Piping Systems.Butt welds butt weld n. A welded butt joint. Noun 1. butt weld - a butt joint that is welded butt-weld butt joint, butt - a joint made by fastening ends together without overlapping of corrosion-resistant PVDF PVDF polyvinylidene difluoride or PP piping can be made precisely with the new SP series of noncontacting infrared welders. They are built by Agru in Austria and marketed here by Asahi/America Inc., Malden, Mass. Computer control of all critical welding welding, process for joining separate pieces of metal in a continuous metallic bond. Cold-pressure welding is accomplished by the application of high pressure at room temperature; forge welding (forging) is done by means of hammering, with the addition of heat. parameters are displayed and adjusted on a touchscreen See touch screen. . After performing a weld, the unit prints out quality-control labels for attaching to the pipe or logbook. Model SP 110 can weld pipe of 0.5 to 4 in. diam., while the SP 250 handles 2.5 to 10 in. |
