Through his outspoken editorials prodding governments into more effective regulation, his attacks on party spirit and patronage, and his promotion of new farming techniques, William Weld became the best known agricultural journalist of his time.
(1824. - 1891) As a farmer, journalist, educator, promoter and conservationist, William Weld made an outstanding contribution to Canadian agriculture. He believed in teaching by example, hence established the first experimental farm in British North America.
Nominated by: D.L. Waterston. Specialty: Education, Livestock - Dairy, Media. Born and educated in England, William Weld emigrated to Canada in 1844 and established Weldwood Farm in Delaware Township, Middlesex County.

Some welds are autogenous. That is, the consist only of remelted base metal because filler metal wasn’t used. But the fact is, most of the time a filler metal is used, and its chemical composition is critical because it can significantly influence the weld metal and the structural properties of the joint. Often the filler metal is designed to produ...
Once you have molten metal and add filler metal, the first grains to solidify are the ones closest to the unmelted base metal. The unmelted base metal nucleates these grains, so they maintain the same crystal orientation. But as the weld continues to solidify, it does so in either a cellular or dendritic growth mode. Either of these growth modes ca...
Right next to the weld metal is the HAZ. In theory, the HAZ may include all the metal raised above ambient temperature. In practice, it’s usually considered the area of the base metal that wasn’t melted but was heated to the point that its microstructure or mechanical properties were altered by the welding heat. For example, a plain carbon steel is...
Base metals usually are specified to take advantage of specific properties or characteristics such as tensile strength, notch toughness, yield strength, corrosion resistance, weight, and density. It’s up to the welding engineer or—more often than not—the welder to use the right process and filler metal or consumable to ensure everything works as pl...
The mixture of filler metal and base metal found in the weld joint is called the weld metal. And while the weld metal’s chemical composition may be similar to that of the base metal (depending on the chemical composition of the filler metal), the microstructures of each are significantly different. This is because the microstructure is more closely...
