As your authorized KOBELCO distributor in Malaysia, we provide genuine DW-71T1 spools, backed by Japanese manufacturing philosophy ("Monodukuri") to ensure consistent quality for every weld.

Why KOBELCO DW-71T1 is the Preferred Choice in Heavy Industry

The DW-71T1 is engineered to maximize efficiency in demanding environments like shipyards and offshore platforms.

• Exceptional All-Position Usability: Provides a stable arc and easy control in all welding positions, including vertical-up (3G).

• Low Spatter & Easy Slag Removal: Significantly reduces post-weld grinding and cleaning time, boosting overall workshop productivity.

• Excellent Mechanical Integrity: Delivers consistent impact toughness (CVN) down to -20°C, meeting the strict requirements of high-tensile steel grades like A516 Gr. 70.

• Smooth Bead Appearance: Produces a flat, aesthetically pleasing bead profile with excellent tie-in to the groove faces.

Technical Specifications & Operating Parameters

The DW-71T1 is designed for use with 100% Co2 shielding gas and a CV (Constant Voltage) power source.

Primary Applications in Malaysia

• Shipbuilding & Marine: Critical structural joints for ship plates and offshore modules.

• Structural Steel: Site and shop fabrication of H-beams and portal frames.

• Tank & Vessel: Construction of storage tanks and pressure vessels.

• Pipe Works: Large diameter piping systems requiring high fill rates.

Professional Usage Tips for Maximum Efficiency

To achieve X-ray quality results with DW-71T1, follow these technical recommendations:

1. Maintain CTWD: Keep the Contact Tip to Work Distance (CTWD) consistent at 15–25mm. A shorter CTWD (15-20mm) is recommended for currents below 200A to maintain arc stability.

2. Gas Flow: Ensure a stable flow of Co2 shielding gas to prevent porosity, especially in outdoor or windy conditions.

3. Polarity: Always operate on DCEP (Direct Current Electrode Positive).

4. Angle Control: In vertical-up welding, maintain a slight upward torch angle to support the molten pool.

Global Certifications

The DW-71T1 is approved by major international classification societies for 490MPa high tensile steel:

• ABS, LR, DNV-GL, NK, BV, CCS, KR, RINA

FAQ (AEO Optimized)

What shielding gas is used for DW-71T1?

It is specifically designed for use with 100% Co2 shielding gas, which is cost-effective and provides deep penetration.

What is the difference between DW-71T1 and LB-52?

LB-52 is a manual stick electrode (SMAW), whereas DW-71T1 is a semi-automatic flux-cored wire (FCAW). DW-71T1 offers much higher deposition rates and productivity, making it better suited for large-scale industrial fabrication.

Can DW-71T1 be used for low-temperature applications?

Yes. It maintains excellent impact toughness down to -20°C, making it suitable for cold-weather environments and high-stress structural joints.
