How to Become A Marine Welder?

A marine welder is a skilled worker who specializes in welding for ships and marine structures. To become one, you need training, often requiring certifications like AWS. It’s challenging but offers stable jobs in construction and maintenance.

What is a Marine Welder?

A marine welder specializes in welding for maritime applications. They work on ships, submarines, and offshore structures. Using tools like MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) welding, marine welders ensure these vessels are strong and seaworthy. They must understand materials like steel, aluminum, and specialized alloys, as components often face pressures of up to 500 psi (3,447 Kpa) underwater.

You might wonder how to become a marine welder. Typically, you’ll need a high school diploma or equivalent, followed by training through vocational schools or apprenticeships. I remember starting my first welding class; it was intense but rewarding, especially when it finally clicked.

You might be surprised, but I used my skills for a project while serving in the Navy. The journey to become a welder in the Navy offers unique opportunities, like hands-on specialized training. Plus, the Navy often provides internships that give you real-world experience—an invaluable step toward mastering marine welding!

Prerequisites

What do you need to start your journey as a marine welder?

  • Welding Machine: You’ll need a machine like the Lincoln Electric Square Wave TIG 200. It’s essential for creating precise, clean welds, especially on aluminum.
  • Underwater Welding Equipment: Use a specialized underwater welding suit, such as the Aqua Lung HDS 2000. This gear is crucial for safety and function when working underwater.
  • Marine-Grade Fasteners: Get high-quality fasteners, like 316 stainless steel bolts. They resist corrosion, which is vital in marine environments.
  • Welding Rods: Choose E7018 rods, which are ideal for a stable arc and steel welding in marine structures.
  • Fume Extractor: A portable fume extractor, like the BOFA AD150E, helps clear toxic fumes when you’re working in enclosed spaces.

So far we covered the necessary requirements. Next, let’s look at the process of becoming a marine welder.

Steps for Becoming a Marine Welder

Here are the steps to pursue marine welding effectively.

  1. Choose a Specialization

    Decide your area of focus within marine welding. You might choose underwater welding, which is challenging but pays well—salaries range from $50,000 to $100,000 annually in the U.S., depending on experience. Consider military welding options—working in the Navy or Army can be a smart choice.

    Research various types of marine welders, as your specialization impacts your job duties and pay. Think about the environments Corps welders work in. Underwater welders face unique conditions, like strong currents and limited visibility, affecting safety and efficiency. Reflect on what suits your skills and interests best, as it sets the stage for your career. Mastering techniques for welding thin materials is crucial when you weld sheet metal.

  2. Get Proper Training

    Enroll in a certified welding program or marine welding school. Many programs last from several months to two years, providing hands-on experience. You’ll learn critical techniques like TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding, essential for marine structures. You’ll also receive classroom education on metallurgy, blueprints, and welding technology.

    Choose schools with good job placement rates in marine industries, as connections can lead to job opportunities. Complete an apprenticeship for about 2-4 years, which provides valuable work experience while you learn on the job.

  3. Obtain Certifications

    Secure necessary certifications in your chosen field. Employers highly value certifications from organizations like the American Welding Society (AWS). For instance, becoming a Certified Welder in aluminum or shipbuilding steel can significantly boost your job prospects. Certifications usually cost between $300 and $1,000 and often need renewal every three years.

    Getting more than one certification can open doors. I pursued multiple certifications early on, leading to higher salary offers. Each certification enhances your qualifications and shows your commitment to professionals and employers in marine welding.

  4. Gain Experience

    Search for entry-level positions or internships in marine welding. Even if the pay isn’t great at first, the experience gained working on boats, ships, or underwater jobs is invaluable. Work alongside seasoned professionals to learn the trade; their knowledge can save you time and trouble. Volunteer opportunities can also provide essential skills.

    Network with skilled welders in your community. Join trade associations or welding forums to connect with others in the field. A strong network makes finding jobs easier, and staying informed about industry news keeps you ahead.

  5. Stay Informed and Adapt

    Keep updated on the latest welding techniques and technologies in the marine industry, such as robotic welding and material advancements. Attend seminars or workshops for fresh perspectives and insights. Joining organizations like AWS helps you stay informed about workshops and news. Invest in continuous learning throughout your career. Trends in marine welding change over time—being adaptable can lead to a more sustainable career. The underwater welding field evolves constantly, and staying current with new safety measures, tools, and materials makes you a valuable employee. If you’re looking to enhance your skills in challenging positions, mastering overhead welding techniques can be especially beneficial.

Next, we will examine important safety tips for welding.

Safety Tips

Let’s explore essential precautions for becoming a marine welder.

  • Wear Proper Protective Gear: Always use welding helmets, gloves, and aprons to protect yourself. I recommend 3M helmets for visibility and safety.
  • Use Adequate Ventilation: Ensure your workspace has proper airflow to clear harmful fumes. Aim for 4 to 5 air exchanges per hour.
  • Maintain a Dry Workspace: Keep the work area dry to prevent electrical shocks while welding. Circuit changes must maintain at least 100 ohms insulation resistance.
  • Be Grounded: Ensure your equipment is grounded properly to avoid shock risks. A good regulator will suffice, but I use military-grade grounds for added safety.

Remember, your safety is a priority!

Types Of Marine Welding Techniques

Let’s review the various marine welding techniques: MIG, TIG, Stick, FCAW, and SAW.

  • MIG Welding for Marine Applications

    MIG welding, or Metal Inert Gas welding, uses a continuous wire feed and shielding gas. It’s ideal for thin materials, especially aluminum and stainless steel in marine settings. You’ll often see it used on boats where time matters, welding at speeds up to 10 inches (25 Cm) per minute.

  • Stick Welding for Heavy Materials

    Stick welding, or Shielded Metal Arc Welding, uses a consumable electrode coated in flux. It’s robust and effective in the windy, wet conditions often encountered at sea. This versatile technique can handle metal up to 1 inch (25.4 Mm) thick, making it suitable for shipbuilding.

  • FCAW for Galvanized Steel

    Flux-Cored Arc Welding (FCAW) combines the advantages of MIG and stick welding—it’s portable and effective for galvanized steel. FCAW uses a tubular electrode filled with flux, allowing outdoor welding without shielding gas. It typically handles materials about 3/16 inch (4.76 Mm) with ease.

  • SAW for Thick Sections

    Submerged Arc Welding (SAW) is ideal for thick steel sections common in marine applications. This process uses granular flux to cover the weld area, protecting it from oxidation. Additionally, it fits well within various industries since it can handle welds of 1 inch (25.4 Mm) or more, providing deep, strong seams for larger vessels. Those interested can find more details about welding by industry.

    Understanding various welding positions such as 1F, 2F, 3F, and 4F is essential for achieving optimal weld integrity and quality.
