Certified Vietnamese 3G/6G Welders for Korean Shipbuilding Companies

Growing Demand for Skilled Welders in South Korea’s Shipbuilding Industry

South Korea remains one of the world’s leading shipbuilding nations, home to major shipbuilders such as HD Hyundai Heavy Industries, Hanwha Ocean, and Samsung Heavy Industries. These companies continue to secure global contracts for LNG carriers, container ships, oil tankers, and offshore structures, creating strong demand for skilled technical workers.

One of the most critical workforce shortages is in welding positions. Korean shipyards require highly skilled welders capable of handling complex welding tasks under strict quality and safety standards. As domestic labor shortages continue, Korean companies increasingly recruit certified foreign welders, especially from Vietnam.

Vietnam has become a trusted source of qualified welding professionals thanks to its strong vocational training system, extensive industrial experience, and growing pool of internationally certified welders. Vietnamese workers have proven their ability to contribute effectively to shipbuilding projects across Asia, the Middle East, and Europe.

Vietnamese welders must obtain AWS (American Society of Welders) certification to be eligible to participate in the assessment and selection process of the Korea Shipbuilding Association (Koshipa).

• Malaysia
• Europe

This international exposure helps workers understand global quality standards, workplace discipline, and safety requirements.

High Productivity and Adaptability

Korean employers value Vietnamese workers for:

• Strong work ethic
• Willingness to learn
• Teamwork capability
• Adaptability to Korean work culture
• Long-term employment commitment

These qualities make Vietnamese welders a preferred workforce solution for shipbuilding subcontractors and major shipyards.

Vietnamese welders participate in a skills assessment test organized by the Korean Shipbuilding Association (Koshipa).

Understanding 3G and 6G Welding Certifications

What Is 3G Welding?

3G welding refers to vertical-position welding where metal plates are welded in an upright position. This certification demonstrates a welder’s ability to control molten metal against gravity while maintaining weld quality.

In shipbuilding, 3G welding is commonly used for:

• Ship hull construction
• Structural steel fabrication
• Bulkhead assembly
• Steel block manufacturing

Because ship structures contain numerous vertical joints, 3G-certified welders are essential to production efficiency.

What Is 6G Welding?

6G welding is widely considered one of the most advanced welding qualifications. It involves welding pipes fixed at a 45-degree angle, requiring welders to perform in multiple positions simultaneously.

6G certification demonstrates mastery of:

• Pipe welding
• Pressure systems
• LNG piping
• Fuel systems
• Hydraulic systems
• Offshore piping networks

Many Korean shipyards place high value on 6G-certified welders due to the complexity of modern vessel construction.

Most Required Welding Processes in Korean Shipyards

Korean shipbuilding companies typically recruit welders skilled in several welding methods.

FCAW (Flux Cored Arc Welding)

FCAW remains one of the most commonly used welding processes in shipbuilding due to its:

• High productivity
• Deep penetration
• Strong weld quality
• Suitability for thick steel plates

Many Korean shipyards specifically recruit FCAW welders with 3G certification.

GMAW / MIG Welding

GMAW welders are frequently employed in:

• Structural fabrication
• Hull construction
• Steel assembly
• Block production

This process allows for efficient welding of large steel components.

GTAW / TIG Welding

TIG welding is critical for:

• Stainless steel piping
• LNG systems
• Precision welding applications
• High-quality pipe joints

Most 6G welders possess GTAW expertise due to its importance in pipe welding.

SMAW Welding

Although less common in high-volume production, SMAW remains important for:

• Maintenance work
• Repairs
• Specialized welding applications

Experienced shipyard welders often possess SMAW qualifications alongside FCAW and GTAW certifications.
