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.
• 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.
