Welding Mild Steel Vertical. When welding vertical down begin at the top of a joint and weld down weaving slightly side to side. Here is mine made from a bit of flat bottom rail the horn and the supporting gusset underneath are made from a bit of 2 half round mild steel bar tapered to a point and 10mm mild steel plate it was stick welded together using some flavour of low hydrogen electrode its been too long ago to remember exactly what i used but its had a serious amount of use over the years without any.
As a rule of thumb in such a welding application stainless steel and mild steel the filler metal you are settling for should have mechanical properties that are equal to or greater than the lesser of both materials you intend to weld. The vertical down technique helps when welding thin metals because the arc penetrates less due to the faster travel speed. Mild Steel and Iron Powder Electrodes 6 Versatile General Purpose Electrode All Positional Welding Capabilities Ideal for the Vertical-Down Welding of Thin Steel Sections Wrought iron furniture Suitable for welding Mild steel plate sheet metal and galvanised iron sheet ducting hoppers tanks pipes and low pressure pipelines.
You will be introduced to the Shielded Metal Arc Welding SMAW process and study the types of power sources electrical characteristics of welding circuits and mild steel and low alloy electrodes.
As far as mild steel stick welding rods go there are only a few that are widely used. Mild Steel and Iron Powder Electrodes 6 Versatile General Purpose Electrode All Positional Welding Capabilities Ideal for the Vertical-Down Welding of Thin Steel Sections Wrought iron furniture Suitable for welding Mild steel plate sheet metal and galvanised iron sheet ducting hoppers tanks pipes and low pressure pipelines. The photo is 1mm steel welded at a power setting normally reserved for 2mm steel. Flat or 1G you drag the rod between 10 to 30 degrees in the direction of your movement.
