Hot-dip galvanized flanged metal corrugated compensator has good flexibility, corrosion resistance
Hot-dip galvanized flanged metal corrugated compensator will be coated with a layer of active flux (referred to as hot-dip galvanized flanged metal corrugated compensator) before welding, under the same welding standards, compared with the conventional TIG welding, can greatly improve the depth of melt (up to 300%). About hot-dip galvanized flanged metal corrugated compensator welding can not open the bevel at a time to obtain a large depth of melt or a weld through, about the thin plate can reduce the welding heat input without changing the case of welding speed.
Now A-TIG welding can be used to weld stainless steel, carbon steel, nickel-based alloys and titanium alloys and other hot-dip galvanized flanged metal corrugated compensators. The key element of A-TIG welding lies in the composition of the hot-dip galvanized flanged metal corrugated compensator. Now commonly used hot-dip galvanized flanged metal corrugated compensator components are mainly oxides, chlorides and fluorides, different hot-dip galvanized flanged metal corrugated compensator and its applicable hot-dip galvanized flanged metal corrugated compensator components are different.
However, because of the importance of this skill, the composition and formulation of hot-dip galvanized flanged metal corrugated compensators are patent-bound in both PWI and EWI and are rarely reported in open publications. Nowadays, the research on A-TIG welding is mainly focused on the study of the mechanism of the effect of hot-dip galvanized flanged metal corrugated compensator and the activation of welding application skills. The weld seam of the hot-dip galvanized flanged metal corrugated compensator coated with SiO2, following the increase of SiO2 coating, the width of the weld channel becomes narrower and the arc pit becomes longer, narrower and deeper. The residual height of the weld channel becomes higher at the junction of the coated hot-dip galvanized flange type metal corrugated compensator, the weld channel metal accumulation, in all hot-dip galvanized flange type metal corrugated compensator, SiO2 has the greatest effect on the welding seam forming.
With the increase of coating amount, the weld width does not change much, and the arc pit does not change significantly. Compared with the weld of hot-dip galvanized flanged metal corrugated compensator, the width of the weld channel also did not change significantly, but the arc pit was larger than that of the hot-dip galvanized flanged metal corrugated compensator. With the addition of TiO2 coating, the appearance of the weld channel does not change much, and the arc pit does not change significantly, similar to that of the hot-dip galvanized flanged metal corrugated compensator. However, the appearance of the weld seam is flatter and more regular, and there is no edge gnawing, which is better than the weld channel forming of hot-dip galvanized flanged metal corrugated compensator.
Hot-dip galvanized flanged metal corrugated compensator has a greater impact on the weld forming. Followed by the hot-dip galvanized flange type metal corrugated compensator coating amount increases, the weld into poor shape, the arc pit does not change much, the weld width does not change much. However, the amount of hot-dip galvanized flanged metal corrugated compensator is increased to show the shortcomings such as biting edge. The effect on the melt depth, compared with the hot-dip galvanized flange type metal corrugated compensator, the above five hot-dip galvanized flange type metal corrugated compensator can increase the melt depth of the weld, and with the increase in the amount of coating, the melt depth also increased accordingly. However, when the coating amount reaches a certain value, the melt depth increases to fullness, and then increases the coating amount, the melt depth decreases instead.
