Two methods of welding were demonstrated; one was the MIG weld and the other a stick weld.Experimental Procedure The procedure of this lab report involves welding two small sheets of metal (each relatively 3x6 inch) together using both MIG and stick welding techniques, then cutting the welded piece to produce two samples.To prepare for the nature of this lab report, a shop lab overview and two welding demonstrations were presented by Mr. Thomas Hatch and Mr. Lucas Jones, who are two of Penn State Altoona’s lab supervisors.Altering the weld surface can be very beneficial to completing a strong lasting weld.Stick welding is a very mobile and useful weld because the coating on the electrode acts as a shield during the weld and coats the top...

Preparation and education on fire safety and emergency management are hence critical and essential.There is no mandatory requirement for fire safety management audits of the buildings.Hence, smoke and burning smell became ‘normal’ at that time due to cutting and welding which as a result, lowered the occupants’ alertness of fire.As the building’s smoke detectors were triggered and the fire alarms rang routinely due to the intermittent welding activities, the 2/F tenant, China Arts & Crafts, wrapped the fire alarms with plastic as to lower the disturbance.Fire Safety Committee – Building Management and Fire Department should seek participation from residents to support fire safety committee for the concerned premises.

On the other hand, the American Welding Society manual provides summarised, but specific guidelines, for ensuring the safety of workers at welding workstations (American Welding Society, 2005).The American Welding Society propose a number of measures (most of which focus on effective ventilation) to mitigate the effects of poisonous fumes exuded from welding processes.Here, it is useful for workers to take measures that ensure correct disposal of ground dust and spent welding rods as proposed by various state laws (American Welding Society, 2005).Fumes exuded during welding processes can adversely affect one’s health on exposure (American Welding Society, 2005).Since AWS guidelines apply to persons who do various welding operations, the ...

Pipe Clamps For clamping pipelines on the outside whilst welding is taking place on straight sections, pipeline flanges or bends.4b) Welding, without the proper precautions, can be a dangerous and unhealthy practice.Because many common welding procedures involve an open electric arc or flame, the risk of burns is significant.External Hydraulic (no tack) Line-up cage clamps lines up pipe for welding to enable the maximum weld to be made without moving the clamp and comes with hand toggle or powerful hydraulic for accurate alignment.Methods like bolts or screws require some type of flange or overlap of parts, so with welding, weight and material savings can be realized.
