Vietnamese Welders 3G/6G for Samsung Heavy Industries, Hanwha Ocean and Hyundai Mipo Subcontractors

South Korea remains one of the world’s leading shipbuilding nations, driven by major companies such as Samsung Heavy Industries, Hanwha Ocean, and Hyundai Mipo. With increasing global orders for LNG carriers, offshore structures, container vessels, naval ships, and specialized marine projects, Korean shipyards are facing a significant shortage of skilled workers.

As a result, Korean shipbuilding companies and their subcontractors are actively seeking experienced foreign workers, particularly qualified Vietnamese welders with 3G and 6G welding skills. Through the E-7-3 Skilled Worker Visa Program, thousands of Vietnamese welders have gained opportunities to work legally in South Korea’s shipbuilding industry while earning attractive salaries and long-term career benefits.

Shipbuilding companies directly inspect, evaluate, and screen the skills of Vietnamese welders.

Growing Demand for Skilled Welders in Korean Shipyards

The Korean shipbuilding industry is currently experiencing a strong growth cycle fueled by global demand for LNG carriers, eco-friendly vessels, offshore platforms, and defense-related shipbuilding projects. Industry reports indicate that labor shortages have become one of the biggest challenges facing Korean shipyards today. Foreign workers now play an increasingly important role in maintaining production schedules and supporting long-term shipbuilding projects.

Major shipbuilding groups including Samsung Heavy Industries, Hanwha Ocean, and HD Hyundai Mipo continue expanding their workforce requirements through direct recruitment and subcontracting partners. Many subcontractors located in Geoje, Ulsan, and other shipbuilding hubs regularly recruit skilled welders from Vietnam under legal employment programs.

Why Vietnamese Welders Are Highly Valued in Korea

Vietnamese welders have earned a strong reputation within Korean industrial sectors due to their technical skills, work ethic, adaptability, and willingness to work in demanding production environments.

Korean employers often prefer Vietnamese workers because they offer:

• Strong welding experience in heavy industry projects
• Experience in shipbuilding and steel fabrication
• Ability to adapt quickly to Korean work standards
• High productivity and discipline
• Competitive labor costs
• Long-term employment commitment
• Good teamwork and communication skills

Many Vietnamese candidates have previously worked in shipyards, steel structure factories, oil and gas projects, mechanical plants, and industrial construction sites. These experiences make them suitable for shipbuilding production lines in South Korea.

What Are 3G and 6G Welding Positions?

3G Welders

3G welding refers to vertical groove welding performed on steel plates positioned vertically. This welding position is commonly used in shipbuilding, steel structures, pressure vessels, and industrial fabrication.

Korean shipyard subcontractors often require 3G welders for:

• Hull block assembly
• Steel structure fabrication
• Marine equipment installation
• Ship section welding
• Offshore platform construction

Candidates with FCAW, SMAW, MIG, or MAG welding experience are particularly in demand.

6G Welders

6G welding is considered one of the highest welding skill levels. The pipe is fixed at a 45-degree angle, requiring welders to perform complex welds in multiple positions.

6G welders are needed for:

• Pipe systems
• LNG projects
• Offshore platforms
• Pressure piping
• Ship engine systems
• Fuel and hydraulic systems

Because of the complexity involved, 6G welders generally receive higher salaries and better opportunities for long-term employment in Korea.

The Korean Shipbuilding Association is assessing the capabilities of Vietnamese welders according to international standards.
