Hard Wire Welding

[Agnewt]

Is "Hard Wire Welding" simply another term for GMAW or MIG welding or am I missing something?

As a follow-up, correct or not, is the definition of "Hard Wire Welding" found in AMSE anywhere? Or any other code or technical document for reference?

I believe the term is referring to hard-surfacing using a MIG process. Is it being applied to resist wear?

Agnewt,
Hardwire is a slang term for GMAW solid wire ER70S the s stands for solid. Additionally, ER70C is also a GMAW process, but the electrode is a cored wire (metal core).

I'll have to agree with hogan666 with one exception and that is hard wire welding is not a slang term but a legtiment word of the trades.

The fact that a "nonstandard" term is recognized by tradespeople or others doesn't make it "standard" terminology.

Likewise, what may be considered to be standard terminology by one organization may not be considered standard terminology by another.

As an example consider the following terms:

Lack of fusion - API 1104 - standard term
Incomplete fusion - AWS A3.0 - standard term

AWS considers "lack of fusion" to be nonstandard terminology and API considers "incomplete fusion" to be nonstandard terminology.

"Hard wire"; I don't know of any organization that considers it to be standard terminology. In general it is a nonstandard term used to describe a solid electrode used for GMAW.

Having worked in the trades for many years, I've heard many terms used that can hardly be considered to be standard terminology and in some case the terms are not to be used in polite company.

"Hard wire" simply means solid rather than flux core GMAW.

That GMAW is also called MIG by welders does not render either acronym illegitimate. One term is simply more precise than the other.

thats true, its hard-surfacing using a MIG process.

Slang for ER70S...not slang for GMAW

Dependant on location. That's why it's a slang or nonstandard term.

In my experience "Hard Wire" welding is solid GMAW wire instead of flux core.
