3.By means of BX1-500 AC arc welding machine,E4303 welding rod,the welding has been performed on the spiral welded pipe with the material of Q235 and specification of 820mmX10mm.
4.The results show that using the right welding parameter and A307 welding rod of high Cr and Ni,the best microstructure and properties of U71Mn and 1Cr18Ni9Ti welding joints of the dissimilar steel can be obtained.
5.The welding performance of homemade wear-resistant cast steel has been studied Base on the weldability tests, the repair welding procedures of wean-resistant cast steel (abrasion-plates) have been made up, The results show that satisfying repair welding quality can be attained with such welding conditions as the low hydrogenous alkalescent welding rod, preheating and slow cooling, strictly maintaining the interbedded temperature of 250~300℃ and controlling welding technique.
6.Based on high stress abrasive grain wear ing situation analysis,C -Cr -Mo is the austenitic alloy overlaying welding m aterial,FAW welding rod,w ith features of good welding process,good cracking resistance and high ma-chining hardening rate which is the i deal welding mater ial instead of austenitic manganese steel.
7.2. using acetylene torch to make tin pewter welding rod melting and bonding with the tin surface to improve the bonding force.
8.This paper compared CO 2 gas shielded arc welding to argon gas shielded arc w elding and arc welding with welding rod in the aspect of welding tie-in test an d their application in engineering mechanism. It was proved that CO 2 gas shiel ded arc welding has the advantage of low cost, high efficiency and better weldin g quality.
9.With the EN polarity time increasing, the liquid metal of welding rod end congregates and its diameter increases, which shows the arc effect of EN polarity for welding rod consumable, Arc creeps up and the brightness of arc column region decreases with EN polarity of AC PMIG welding, and the brightness of arc column region increases with background level of EP polarity. This kind of AC arc is propitious to reduce the arc plasma jet force and the arc force on molten pool.
