Dry Ice Blasting

Dear Readers,

Wish You a Happy Winter, During winter let us discuss about surface cleaning with dry ice!
This new development is quickly expanding around the world. One system uses small rice pellets of dry ice shooting them out of the jet nozzle with compressed air.
Dry ice blasting is known by several names like dry ice cleaning, CO2 blasting and dry ice dusting. It is a kind of carbon di oxide cleaning, where dry ice in the solid form of carbon di oxide, is accelerated in a pressurised stream and directed in the surface in order to clean it. This method is similar to other forms of abrasive blasting such as sandblasting, or soda blasting substituted for dry ice as a blasting medium.
This method is superior to sandblasting because the dry ice is soft enough not to pit or damage the underlying surface. Since the dry ice evaporates completely as a gas it leaves no wastes. Only the material being removed must be disposed of.
Dry ice blasting is the superior alternative to sand blasting, short blasting, soda blasting, water blasting and hand cleaning.
Advantages of dry ice blasting:
·         No preparation required prior to cleaning
·         No need to dismantle machines for cleaning. The pellets easily reach into the smallest nooks and corners.

·         Minimal machine downtimes

·         Environmentally friendly cleaning

·         Without additional chemicals or spray agents

·         Surface are not damaged

·         No residues

1.   The loud noise produced requires protective ear equipment and may cause irritation to other people nearby. Although new machines are much quitter.

2.   Effective can only occur in a straight line of sight from the dry ice jet nozzle. Sometimes parts can be dissembled to help.

3.   Large amount of carbon di oxide are released which can be harmful if not ventilated out of space.

Welding Positions

Dear Readers,
In Construction Industry any conversation around welding starts with a discussion on welding position, it is mandatory to qualify the welder. At site welding activity starts with welder qualification. The American Welding Society (AWS) has defined the four basic welding positions. The same positions is followed in construction as well as welding related industries.
The four basic welding positions are: flat, horizontal, vertical, and overhead. An Alpha numeric is used to identify the position. Eg. 4F & 2G First number is used to define the position and alphabetic is used for the weld.

1 = Flat Position
2 = Horizontal Position
3 = Vertical Position
4 = Overhead Position
F = Fillet Weld
G = Groove Weld

1 refers to a flat position, either 1F or 1G
2 refers to a horizontal position, either 2F or 2G
3 is a vertical position, either 3F or 3G
4 is an overhead position, either 4F or 4G

The 1G and 5G horizontal and 2G vertical positions refer to the pipe position.
6G is an inclined position

Flat Position Welding: This type of welding is performed from the upper side of the joint. The face of the weld is approximately horizontal. The common term for this kind of weld is called, 'flat position' but it is also referred to as the 'down hand' position.

Horizontal Position Welding: In horizontal welding, the weld axis is approximately horizontal, but the weld type dictates the complete definition. For a fillet weld, welding is performed on the upper side of an approximately horizontal surface and against an approximately vertical surface. For a groove weld, the face of the weld lies in an approximately vertical plane.

Vertical Position Welding: In vertical position welding, the axis of the weld is approximately vertical. When welding is done on a vertical surface, the molten metal has a tendency to run downward and pile up.

Overhead Position Welding: Overhead welding is performed from the underside of a joint. In overhead welding, the metal deposited tends to drop or sag on the plate, causing the bead to have a high crown.

The welding positions explained above are commonly used by codes and industrial practice when qualifying welders and job execution.
