I'm using Oerlikon Supercito 7018 but my welders complain saying the welding characteristics have changed, is there another electrode that I can use that meet our boiler code requirements, F4 and A1?

The purpose of filler metal specifications is that qualified products are interchangeable for code work. Thus AWS E7018-1, iron powder, hydrogen-controlled, coated welding electrodes, complete with

We're welding carbon steel to EN19 type high strength low alloy steel using 308L flux cored wire, is this correct?

For welding carbon steel to an EN19 type high strength low alloy steel (AISI 4130 type), you should use a 309LMo type FCW and make sure that there is absolutely no source of moisture anywhere, so good

We have been asked to weld 17-4PH Stainless Steel, what TIG filler wire would you recommend?

Martensitic precipitation hardening 17-4PH stainless engineering steel possesses very good weld ability and can be treated like a 304 grade for welding procedure. Generally, the most widely used

We are welding 4130 low alloy steel, which TIG filler wire should we use?

AISI 4140 is a widely used high-strength, low alloy, structural steel. It's also commonly used alongside AIS 4130 steel. These are Cr-Mo steels: the 40 and 30 indicate 0.40 and 0.30 typical carbon

Is Bohler A31 to BS 2901 Pt1 A31 capable of giving impact value of min 27J at -46 degree Celsius?

If the filler metal is used with GTAW using pure argon shielding, and relatively low dilution, then the low temperature toughness requirement can be achieved. 27J is generally achievable at -20

Repairing cracks in cast steel, which electrode should I use?

NiCi is a 99% Ni coated electrode, designed to weld higher carbon cast steel components, (AWS A5.15, ENi-CI) it contains high carbon content. It expands as the weld deposit freezes and causes

Welding nickel alloy 625 to 321 stainless steel, which TIG filler rod do I need to use?

The dissimilar joint between alloy 625 to 321 titanium-stabilised, austenitic stainless steel can be welded using

Welding Maraging Steel, what is the best welding rod to use?

MW 309L Stainless Steel

Low hydrogen welding rods with a 'basic' flux coating, what does this mean?

'Basic' in this context is an applied chemistry description and means usually more calcium carbonate type additions to the flux coating and less titanates. This reduces the hydrogen potential of the

We need a low hydrogen welding rod that is more user friendly for welders, do you offer such a product?

We would recommend that you consider looking at the

We're welding HE30 aluminium, which TIG filler wire do we need?

HE30 is type 6082. It is very common and crops up all of the time. The filler metal that is widely applied is MW 4043, which is available in a large variety of sizes below.

I'm welding aluminium 5754, which grade of TIG filler wire do I need?

We would recommend MW

Welding with austenitic stainless steel, what are the benefits?

Stainless steels are iron alloys with added chromium and nickel.

A minimum of 10-12 wt% chromium content is required to produce rusting resistance. As more Chromium is

What are Ferritic stainless steels and what industries are they used?

The 400 series of plain chromium stainless steel materials includes ferritic, martensitic and some precipitation hardening stainless alloys. They are iron alloys that contain more than 10wt% of

What are Martensitic stainless steels and when are they used in the welding industry?

The 400 series of hardenable Martensitic stainless engineering high-alloy-iron materials typically contain 11.5 to 18wt% chromium with a variety of carbon levels. Unlike the austenitic and ferritic

What are the benefits of using Duplex Stainless Steel welding wires?

A relatively modern group of stainless engineering steels is the Duplex series of alloys. These material consist of approximately 50:50 austenite and ferrite phases in the matrix, hence their

What are the best TIG welding rods to use for repairing alloy wheels?

The highest strength Al-Mg alloy filler metal is always 5556 (triple 5 six is the common name), it was developed for the UK Navy, it's the best. It's both preferred and superior to 5356. 5556,

We are hardfacing cast steel using traditional 600 type hard facing TIG welding wire, is there something available with higher impact resistance while maintaining 55-60 rockwell?

A hard-facing alternative to the cobalt alloy filler wire is AWS A5.21 ERNiCr-B or ERNiCr-C. Chemistry w% approximately: Ni bal, Cr12, C 0.5 ,Si 3.5, VPN 50-56 depending on dilution, heat input and
