The key to increasing tube mill weld speed is to provide consistent roll forming of the strip material for edge presentation at a weld station. This allows the TIG beam welding process to maximize the mill output. Weld speed depends on: 1. Strip material composition and weldability and certification tolerance limits. 2.

Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.

Aug 25, 2018. #1. Dear All, I have a project which involves moving a small hole in a piece of steel. The part is fairly easy to work so I assume that it's mild steel. I thought that the best way of tackling this would be to fill up the hole and then mill a new one in the desired position. I dug out my MIG and plugged the hole with weld until ...

This would increase the speed of a mill from 200 to 400 feet per minute without any increase in weld power, or if speed were kept constant, would cut power costs in half. Since the average annual cost of impeders for a single 2" tube mill is less than $8,000.00, "cheap" impeders are frequently a very costly item.

Stick welding is the best welding process to weld through mill scale. The stick welding rods are covered with a thick layer of flux material. The flux contains many deoxidizers and other impurity scavengers that can remove mill scale from the puddle. Stick welding (SMAW or MMA) always creates a forceful arc.

Tube mills produce thin-wall pipe and tube by taking a continuous strip of material and roll forming along the length of the strip until the edges meet and mate together at a weld station. At this weld point, the welding process melts and fuses the edges of the strip together, and the material exits the weld station as welded tube.
