Abstract

The present invention relates to a structure steel welding rod and its production process. The welding rod is characterized by that the coating mixture comprises ilmenite 30-38 wt%, rutile 12-15 wt%, titanium white powder 1-4 wt%, white clay 2-4 wt%, sepiolite 8-11 wt%, feldspar 8-11 wt%, mica 5-8 wt%, marble 3-6 wt%, magnesia-calcium powder 4-8 wt%, medium-carbon ferromanganese 7-10 wt%, ferrotitanium 1-4 wt%, wood flour 1-3 wt%, Chinese yam powder 1-4 wt% and microcrystallite 1-2 wt%. Wet welding rod is dried with coal gas produced by industrial gas producer. The welding rod is used widely in steel structure and has high welding efficiency and low production cost.

Description

Technical field: [0001] The invention relates to a welding rod and a manufacturing method thereof. In particular, a novel welding rod for welding structural steel and a manufacturing method thereof. Background technique: [0002] The performance of conventional structural steel electrodes mainly refers to the performance of arc ignition, arc stability and re-strike during welding, the shape of weld seam, the performance of electrode slag removal, the degree of welding slag spatter, the efficiency of electrode melting and the adaptability of electrodes to various welding positions. Wait. The currently used structural steel electrodes are limited in the width of the weld seam when welding, and when the weld seam is too wide or too narrow, the slag coverage is not very good. Moreover, the range of allowable current intensity during welding is relatively narrow, and the welding speed is slow, which cannot meet the needs of fast-paced projects. Since the current welding rods a...
