Welding Skills

A Welder permanently joins pieces of metal with metal filler, using heat and/or pressure. Welders join parts being manufactured, they build structures and repair broken or cracked parts, according to specifications.

Job Related Skills, Interests and Values

• using and maintaining tools, material handling equipment and welding equipment;

• reading and interpreting blueprints;

• acquiring thorough knowledge of arc, gas and resistance welding theory ;

• laying out, cutting and forming metals to specifications;

• preparing the work site;

• fitting sub-assemblies and assemblies together and preparing assemblies for welding ;

• welding using shielded metal arc welding, gas metal arc welding, gas tungsten arc welding, flux core or metal core arc welding, submerged arc welding and plasma arc welding processes;

• carrying out special processes such as welding studs and brazing;

• ensuring quality of product/process before, during and after welding;

What Preparation and Training Do You Need?

To become a Welder you should complete Grade 12 with credits in mathematics (particularly technical math) and some shop courses. In Ontario, welding is an unrestricted trade; completion of an apprenticeship could take approximately 3 years including 3 periods of 8 weeks (720 hours) in-school theory. Upon successful completion of the training agreement, you will receive a Certificate of Apprenticeship.

What’s Your Future as a Welder?

Most workers in this occupation work full-time, sometimes in shift work, usually indoors. Those with the ability to work with high-technology welding applications may have better employment opportunities. The bulk of employment opportunities are predicted to occur in the non-electrical, machinery, construction and metal-fabricating industries. Some workers will become self-employed. Examples of companies that employ welders include:

• Fabricating shops;

• Manufacturers of structural steel and platework;

• Construction industries;

• Boilers;

• Heavy machinery contractors;

• Aircraft contractors;

• Ship building and other transportation contractors;

• Specialized welding shops.

Wage Rate

• as an apprentice you would start at a wage rate less than that of a journeyperson

• this rate increases gradually as you gain competency

• the wage range for fully qualified welders according to the Peel Halton Dufferin HRDC Wage Book is between $9.50/hr to $16.18/hr, with a median salary of $12.50/hr.

After reading activity

Revise the information of Unit1 and make a list of the things welders should be able to do and places they can work at.


Ask Yourself: Is Working as a Welder For You?

Are you good at preparing and planning a job from start to finish?

^ Yes ^ No

Can you look at a diagram or shop drawing and visualize how things come together?

^ Yes ^ No

Do you like figuring out what’s wrong with something and then repairing it?

^ Yes ^ No

Are you able to bend, stretch, kneel, stand for long periods and lift material and supplies?

^ Yes ^ No

Would it bother you to work around dangerous gases and intense heat?

^ Yes ^ No

Do you have good hand/eye coordination to guide a welding arc along the edges of metal?

^ Yes ^ No

If you answered Yes to most of these questions, welder may be for you! Lead-in

You already know what sort of skills you should have to be a welder. Now think of the answers to the following questions:

1. How long should a person be trained to become a skilled welder?

2. Do you think that a welder should be able to use all kinds of welding?

3. What is more interesting to you personally: welding techniques, welding inspection (other)?
