Weld shape and size when submerged arc welding

Weld shape and size "1. welding parameters influence when submerged arc welding seam shapes and sizes of sleep: the concept of weld shape (1) weld shape and welding parameters for the weld metal lung sectional Mindanao , as shown in Figure 3-2 'b to weld width; h for the base metal penetration depth, called weld thickness;. deposited stack height of weld, the weld reinforcement is called Mindanao. h ratio of stone and weld thickness, the weld shape factor called Shanghai, namely, basic metals and molten weld cross sectional area of ??the second cross-sectional area F (Fm + F}) ratio, called the weld fusion than y, that is, Fl where one cross-sectional area of ??the weld filler metal. affect weld shape factor Shanghai weld internal quality is very large, choose the time when Shanghai, will produce internal weld porosity, slag , cracks and other defects. Shanghai value can vary between 5 and --- at D. 10. In general, the control of Shanghai = 1.3-2 is more appropriate for the escape of gas and molten slag or prevent cracks Defects are advantageous. fusion welding Y main impact than the chemical composition, microstructure and mechanical properties. Changes in Y reflects the filler metal in the proportion of the entire weld metal has occurred, which led to weld composition numerical range .Y organizational change and performance, and can be in the ID% -.} changes within 8b0o range of large submerged Y Fan is generally about 60%} 70% of the weld. size form factor sand and fusion than Y values, depending on the main parameters of the welding process parameters submerged arc welding process are: welding current, arc welding power and speed Also, as the wire diameter, welding preheat temperature etc., also belong welding process parameters.
