Different Types of Welding Process With Diagram

This type of welding will require different metals to be coined when they are at their melting point. There are various processes that can be included in this type of welding but it will be ideal to focus on those that are used more. Cold Welding – This type of welding is done at room temperature and will require high pressure so that it can be done successfully.

Blast furnace scabs | British Steel

A high lime chemistry increases the melting point of the slag, which can mix with the excess fines to form a sticky mixture which can adhere to the furnace wall. What issues can scabs cause? The ideal blast furnace burden should have a large cross-sectional area for the carbon monoxide gas to do its magic and react with the raw materials.
