How do I choose a welding consumable?

Factors for Selecting the Right Stick Electrode

1. Base metal properties.
2. Tensile strength.
3. Welding current.
4. Base metal thickness, shape and joint fit-up.
5. Welding position.
6. Specification and service conditions.
7. Environmental job conditions.

What are the similarities and differences between consumable and non consumable electrodes?

A consumable electrode itself melts down during welding and subsequently deposits on the weld bead. A non-consumable electrode does not melt down or deposit on the weld bead. It remains intact throughout the welding.

What is the difference between consumable and Nonconsumable?

A non-consumable resource is an item that you have a limited quantity of and something that you reuse such as a projector, electronic equipment, or chairs. A consumable resource is something you keep a quantity of on stock such as information packets, workbooks, or art materials.

What are consumable electrodes made of?

The key characteristics of consumable electrodes are the following: they have lower melting points, they are usually used in metal inert gas (MIG) welding, they are typically made of mild steel or nickel steel and they are used in arc welding.

What are welding consumables?

Welding is the process of joining metals and thermoplastics by means of coalescence. Flux and filler metals together are known as welding consumables. Stick electrode, flux-cored wires, solid wires, SAW wires and fluxes are some of the welding consumables employed during the welding process.

What is the difference between consumable and non consumable arc welding?

Consumable electrodes become part of the weld bond itself. In contrast, non-consumable electrodes are not consumed during welding, with a separate welding rod serving as the filler metal that melts and joins the metals together. For instance, non-consumable electrodes are used in TIG welding.

What are consumables in welding?

WELDING CONSUMABLES. In Welding, substances called filler materials or consumables are used. As the name implies, these substances provide a filler or a body of molten materials that provides a strong bond to be formed between the base metals used.

What are consumable electrodes in welding?

The electrodes used in arc welding can generally be categorized as consumable or non-consumable. Consumable electrodes become part of the weld bond itself. The electrode serves as the filler metal and melts along with the metals to be welded together. For instance, non-consumable electrodes are used in TIG welding.

What is the difference between consumable and non consumable welding electrodes?

Differences between consumable and non-consumable electrode. A consumable electrode itself melts down during welding and subsequently deposits on the weld bead. A non-consumable electrode does not melt down or deposit on the weld bead. It remains intact throughout the welding.

What is the role of the consumable in arc welding?

The role of the consumable in arc welding is to not only fill in the seam, but also stabilize the flame of the electric arc. As you’ll learn in a welding program, the type of consumable used can vary between a cored wire, solid wire, or rod electrode depending on the job.

What are the consumable parts of a gas welding machine?

Moving on to the main consumable parts, these usually comprise of a liner, contact tip, gas nozzle and gas diffuser. It is these parts that are primarily responsible for consistent feeding of the welding wire, maintaining a gas shield and creating the electrical conductivity necessary for a good welding arc.

What are the features of completed welds?

Features of Completed Welds . Butt weld. Fillet weld. Parent Metal. Metal to be joined or surfaced by welding, braze welding or brazing. Filler Metal. Metal added during welding, braze welding, brazing or surfacing. Weld Metal. All metal melted during the making of a weld and retained in the weld. Heat Affected Zone (HAZ)
