The Royal Arc 71T-1 is a high-quality, rutile-type Flux-Cored Arc Welding (FCAW) wire designed for all-position welding of mild and medium-tensile steels. It is one of the most widely used wires in the industry due to its versatility and ease of use. Below is a detailed breakdown of its characteristics, applications, and technical specifications. Core Characteristics The “71T-1” classification tells us several things: the 7 indicates a minimum tensile strength of 70,000 psi, the 1 means it can be used in all positions (flat, horizontal, vertical, and overhead), and the T-1 refers to the flux type (rutile) and its usability characteristics. All-Position Capability: The slag is designed to freeze quickly, which helps support the molten weld pool when welding vertically up or overhead. Arc Performance: It provides a very stable, smooth spray-like arc with minimal spatter. Slag Removal: The slag is generally self-peeling or very easy to remove, leaving a clean, bright weld bead with a smooth ripple profile. Shielding Gas: This wire requires an external shielding gas, typically either 100% CO 2 ​ or a 75−80% Argon/Balance CO 2 ​ mixture. Technical Specifications Feature Details AWS Classification AWS A5.20 E71T-1C / E71T-1M Polarity DC+ (DCEP - Electrode Positive) Shielding Gas 100% CO 2 ​ or Argon/CO 2 ​ Mix Tensile Strength ≈480−600 MPa Yield Strength ≈400 MPa min. Elongation 22%−30% Export to Sheets Common Applications Because of its high deposition rate and efficiency compared to traditional stick (SMAW) welding, the Royal Arc 71T-1 is a “workhorse” in the following sectors: Shipbuilding and Marine Repairs: Excellent for long seams and out-of-position hull work. Structural Steel Fabrication: Used in building frames, bridges, and trusses. General Manufacturing: Ideal for heavy machinery, earth-moving equipment, and pressure vessels. Storage Tanks: Highly effective for circumferential and longitudinal welds on large tanks. Best Practices for Use Wire Stick-Out: Maintain a “Contact Tip to Work Distance” (CTWD) of roughly 15–20mm. A stick-out that is too short can cause bird-nesting or tip fusion. Storage: Like all flux-cored wires, it should be stored in a dry environment to prevent moisture pickup in the flux, which can lead to hydrogen-induced cracking or porosity. Ventilation: FCAW produces more smoke/fume than MIG welding; ensure proper extraction or use in well-ventilated areas.

The Rasi EM12K is a high-performance, fluoride-basic type agglomerated flux designed specifically for high-quality welding of medium and high-tensile steels. When paired with EM12K wire, it produces a weld metal that offers excellent radiographic soundness and mechanical properties, making it the preferred choice for industrial applications where safety and durability are paramount.

SUPERMIG 316L SUPERMIG 316L is an extra low carbon 19 Cr/ 12 Ni/ 3 Mo type stainless steel solid wire similar in composition to ER 316L. Suitable for the welding or surfacing of having similar compositions. The weld metal has excellent creep strength up to 850°C. Ferrite controlled between 5 to 10%. SIZE- 0.8mm, 1.2mm
