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 release certification Meet the code


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 quality gas shielding and clean


Martensitic precipitation hardening 17-4PH stainless engineering steel possesses very good weldability and can be treated like a 304 grade for welding procedure. Generally, the most widely used filler wire is 309L or 309LMo. 312 filler


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


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 normally achievable at -20 Deg C, using careful welding procedures,


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


The dissimilar joint between alloy 625 to 321 titanium-stabilised, austenitic stainless steel can be welded using Masterweld 625 (ERNiCrMo-3) Nickel Alloy TIG Wire. You will notice we have a variety of sizes in stock for different


Masterweld 309L Stainless Steel MMA Electrodes would be perfectly adequate to weld this.

Welding Tips and Techniques

No preheat needed, clean preparation very important before welding.


'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 arc zone.

The term " basic"


We would recommend that you consider looking at Eurotrod BD22 7016 Dual Coated MMA Electrodes. It is a excellent solution to the dilemma of having a "basic flux" for hydrogen control on the inner layer and a " rutile flux" for improved


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

Welding Tips and


We would recommend Masterweld 5556 TIG Filler wire. The higher Mg content in 5556 helps to offset the 3 Mg in the 5754 alloy and steers it away from the 3Mg critical level. There is a matching filler alloy manufactured, but not in


Stainless steels are iron alloys with added chromium and nickel.

A minimum of 10-12 wt % chromium content is required in order to produce rusting resistance. As more Chromium is added beyond this level a higher degree of


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 chromium. The chromium forms a


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 grades, the Martensitic series have a


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 descriptive dual-phase name. The dual phase


The highest strength Al-Mg alloy filler metal is always 5556 (triple 5 six is the common name) This was developed for the UK Navy, It is the best. It is preferred & superior to 5356 in many ways. It gives the highest, as-welded


A hard-facing alternative to the cobalt alloy filler wire is AWS A5.21 ERNiCr-B or ERNiCr-C. Chemistry wt% approx.: Ni bal, Cr12, C 0.5 ,Si 3.5, VPN 50-56 depending on dilution and heat input and arc-length.( for the NiCr-B) This
