Walking the cup is a term related to TIG welding whereas any good TIG welder will use. It is a term describing using a cup sized for the groove. You would then place the cup directly on the bevels and weave. This provides stability for the root, hot pass and any filler passes where you can get the cup into the groove.
What size cup is best for walking the cup?
Depending on the joint configuration, operators need to adjust the size of cup used for the root pass, but in most cases (and for the sake of this discussion), a number six (3/8 inch) cup would be appropriate.
What is the difference in MIG and TIG welding?
The difference between the two is the way the arc is used. MIG (metal inert gas) welding uses a feed wire that constantly moves through the gun to create the spark, then melts to form the weld. TIG (tungsten inert gas) welding uses long rods to fuse two metals directly together.
Is walking the cup hard?
It’s definitely possible, just more difficult. Resting your cup on your workpiece allows you to pivot your torch in a lazy figure 8 pattern. Often beginners will push down hard on their cup. In reality you only need to rotate the cup against the material with a little bit of pressure.When should you walk the cup?
Walking the Cup is a Tig welding technique When the cup is rested inside a groove or the 2 sides of a tee joint, or when the cup is rested on the outside of a pipe or on a flat surface .
Do you push or pull when TIG welding?
With TIG welding, use argon gas whether joining stainless steel, aluminum or steel. While push and pull both work well for MIG welding, with TIG, always use the push method.
How much do TIG pipe Welders make?
The average tig pipe welder salary in the USA is $44,363 per year or $22.75 per hour. Entry level positions start at $39,000 per year while most experienced workers make up to $66,300 per year.
What is a pipe welding?
Pipe welding is a method for joining two pipes together. Welding techniques used for pipes include arc welding processes including MIG welding and TIG welding.What are TIG welding cups made of?
Gas cups (also known as nozzles) used in TIG welding are manufactured from ceramic materials of which there are two main types; Aluminum Oxide (pink color) and Aluminum Silicate (white or gray color). ESAB identifies these cups as High Impact and Ceramic Cups.
Does welding melt metal?As opposed to brazing and soldering, which do not melt the base metal, welding is a high heat process which melts the base material. Typically with the addition of a filler material. … Pressure can also be used to produce a weld, either alongside the heat or by itself.
Article first time published onWhat is freehand welding?
Free Hand TIG Welding The weave takes the same motion, but when you weld freehand you don’t touch the workpiece with the cup. It takes more dexterity because you don’t have the cup steadying the torch and helping maintain a constant arc length.
Is TIG stronger than MIG?
Bottom Line. TIG welding produces cleaner and more precise welds than MIG welding or other Arc welding methods, making it the strongest. That said, different welding jobs may require different methods, while TIG is generally stronger and higher in quality, you should use MIG or another method if the job calls for it.
What is the strongest weld joint?
The absolute strongest weld that can be made in routine applications would be a type of weld made via the welding technique of Tungsten Inert Gas (TIG) Welding, also known as GTAW welding. TIG welders are known for creating clean and strong welds.
Is stick welding stronger than MIG?
Some argue that stick welding is stronger than MIG welding, since it offers better penetration for thicker materials. However, MIG welding can provide good welds despite not being as effective on thicker metals, and is better for joining thinner metals with a good finish and less risk of burn-through.
How does a MIG welder work?
Metal Inert Gas (MIG) welding is an arc welding process that uses a continuous solid wire electrode heated and fed into the weld pool from a welding gun. … The gun feeds a shielding gas alongside the electrode helping protect the weld pool from airborne contaminants.
Which type of welding pays the most?
- Welder helper. National average salary: $13.53 per hour. …
- MIG welder. National average salary: $16.24 per hour. …
- Fabricator/welder. National average salary: $17.76 per hour. …
- Welder. National average salary: $17.90 per hour. …

- Pipe welder.
What is the highest level of welding?
The highest level for them is usually 6G, which means they can weld 360 degrees around a pipe that doesn’t move. Producing this weld to the satisfaction of a certified welding inspector is tough sledding for a beginner. Nevertheless, a 6G certification is considered the gold standard of the welding profession.
How much do oil rig welders make?
Average pay for oil welders across the country is about $70,000 per year. While salaries start between $40,000 and $60,000 per year, with the right skills, experience, and certifications, welders can make as much as $200,000 annually working on oil rigs.
What is cup size in welding?
Cup size (sometimes referred to as nozzle or lava cones), play an intricate part in welding pipe open butt groove joints. The size and length of the cup being used is normally determined by the joint design and root opening. Wall thickness and joint design is the biggest determining factor.
What do different size TIG cups do?
For example, the smaller the pipe diameter, the shorter the selected nozzle. Larger gas nozzle diameter – more shielding gas cover: The diameter of the gas nozzle, or its opening, determines the size of the area around the weld seam that will be covered by shielding gas.
