When it comes to the MIG welding position one of the most difficult techniques is the vertical up position as you need to have the MIG gun pointed upwards at an angle of 35-45 degrees. This is popular with flat horizontal and overhead stick welding.

Hold the MIG gun at a 90-degree angle to each piece of metal when welding a butt joint to direct the heat and filler metal equally to each piece of material.

. 7 rows With a MIG welder you can weld in the vertical position if you use the common short-circuit. Working uphill the welder can use a variety of patterns to spread the filler metal into the joint. 80 is usedthe sch40 can be used but not always.

Like weaving there is a separate forehand and backhand method for each pattern. Weaving is a side to side motion. A vertical weld is much easier to make look good than a horizontal flat position weld.

The figure eight and zigzag weaving motion is a good technique for making a cover pass when you are in the vertical welding position of flat welding position. When welding vertical up you need to build a shelf of weld to work upward on. Cross country pipe lines often use down hand.

The chart below includes all 8 techniques above plus two more the V and the upside down V which can be used uphill. Butt weld a 180-degree joint. Most single-phase MIG welding machines work only.

Thick pipe at least sch. Each welding process favors different weaving patterns for uphill welding. Circles are a circular or oval motion.

The 3 patterns that work the best are. If I have an L shaped area to weld with one of the two sides being vertical I will run a J type pattern ware I creat a ramp with each stroke to run up and hold it aginst the vertical piece. This pattern greats a flat stack of dimes.

The problem with vertical down is the weld can overlap. Those options are comprised of the circle holding still and whipping. Vertical MIG welding is one of the most difficult and tiring welding position to master.

For me I dont have to do as much movement just drop down a little and gravity brings the puddle of the previous dime to you so you dont have to overlap very much. MIG welding is very easy to learn but since it is a semi-automatic process much of the skill relies on machine set-up. Vertical 7018 welding can benefit from using a weave type pattern.

Again as we go against gravity it is better to reduce the voltage and amperage to about 10-15 of its initial values. Stringers are used mostly on thin stock or on thick stock where you plan multiple passes. ALWAYS go downhill with gravity.

The MIG gun handle should be pointed up between 35 to 45 degrees. Whipping is distinctly different from weaving and the circle pattern technique is a combination of the two. It is accomplished by dragging the gun along the weld seam at the proper rate to allow fusion to occur.

MIG welding requires the weld to be shielded from the atmosphere. Thus you will need to take certain considerations such as a reduction in amperage of your machine at first because the hotter the puddle the more easily it will drop to the ground. Shows how to make Vertical fillet and prepared butt welds and Overhead fillet and prepared butt welds with a MIG Welder.

And during vertical up GMAW welding the welder needs to create a weld shield to move upwards. A vertical weld can be performed in. Pulling the trigger electrically energizes the welding wire and starts the motor drive feeding the wire automatically as you weld.

When you should not weave for MIG welding you have three other options. Sure there are other ways of making a good looking vertical uphill weld but for ensuring penetration as well as making a good looking uniform weld the upside down V is a very good way to go. If you need help with welding vertical up it always a.

The hand-held gun is the business end of a MIG machine. There are ways to weld vertical down and it takes time to learn. When it comes to vertical welding doing both up and downward will be hard.

It may look good but itmay not be fused. Slag is helpful to support the puddle when welding uphill. You dont want to pause in the middle and beware going beyond the edge of your weld joint as you move back.

This can result in lack of fusionbetween welds. The upside down V is one of the most effective techniques for vertical mig welding of lap and tee fillet welds. If your having to weld vertical up with mig and your welding anything thicker then 14 material run a dual shield wire e71t and not only will the weld appearance be much bettar but you can easily weld vertical up and not have the puddle fall out.

Some welders prefer to push the puddle and some pull the puddle. The gun has a trigger that controls several functions simultaneously. The key to the upside down V uphill MIG welding technique is tracing the edge of the puddle.

The vertical up weld in MIG is typically very convex. You might need a pre-weld setup ready to make sure your vertical welding can be done efficiently and with ease.

One reason why MIG welding is limited when vertical welding is that MIG wires dont generate slag. 05-02-2012 0458 PM. 04-15-2012 1111 AM.

Vertical up is the most difficult of the MIG welding positions. Vertical Up MIG Welding Techniques. The whip a back and forth motion.

Thus the welder can use many different patterns to spread the filler material on the alloy surfaces. Vertical Up MIG Welding Technique. Hold the gun at a 90-degree angle to the workpiece directing the filler metal straight into the joint but dont forget to include your travel angle of 5 to 15 degrees.

Demonstrates MIG welding techniques. Forehand vs Back-Hand. Weave type pattern is preferred in vertical welding.

The straight line bead you refer to is called a stringer bead. Vertical welding position requires you to work against the force of gravity. 10 Techniques To Practice.

Use the right wire. This pattern makes a nice contour to the weld with the end result looking like butterfly wings. Weaves are much easier on vertical tests but sometimes CWIs will only allow stringer passes.

MIG welding beads are universal as there are so many techniques for establishing a good weld. If you insist on running hard wire on vertical up then. The short circuit mode or short-arc is the most popular.

Once you have that down you are ready to weld. In other words you gradually weld uphill by moving your arc to the front of the puddle tracing it back and forth uphill in a steady V motion. The characteristic appearance is a smooth ripple-free bead with a rounded appearance.
