The Building and Construction Authority, Singapore has come up with a set of guidelines for welding filler metal (electrodes and wire) to ensure the quality of welding is not compromised in Singapore’s building structures. Below is the highlighted portion with regards to welding filler metal requirements. BCA BC1:2012 Design Guide on Use of Alternative Structural Steel The actual performance and compliance of the steel materials with the nominal specifications stipulated in t

In this article, we will look at the common construction grade timber that is available in Singapore market and do a comparison between the different timber types, namely Balau, Kapur, Keruing and Chengal. Lastly, we will look at Bakau Piles which is commonly used for soil reinforcement purpose. Balau - Hardwood Pricing: Moderate High Pricing Properties: Hard, heavy and very dense with high bending and crushing strengths. The wood is moderately difficult to work with machines

Most construction sites requires the use of excavator to remove the mineral/soil before the actual construction can begin. The abrasion between the mineral and the excavator will result in the wear of bucket as well as the teeth. It is very important for the welder to use the correct welding consumable for the repair and protection of the worn-out parts and areas, this will reduce the down time of the excavator thus increasing the productivity of the excavator. Most welders h

When wood is exposed outdoor, it is vulnerable to the effects of the weather, moisture, wood decay and insect attacks. You can protect your wood and extend the service life and help maintain its natural appearance by 2 different methods. 1) Brushing On Wood Preservative Solution 2) Tanalith CCA Preservation Pressure Treatment In the first method, wood preservative solutions is brushed onto the wood surface itself. The wood preservative solution will penetrate into the wood an

ACHIEVE SUPERIOR WELDS WITH SEAMLESS FLUX-CORED WIRE - Low Hydrogen Content, Superior Against Porosity & Cracking - High Quality Weld, Cost Savings Nippon Steel Welding & Engineering (NSWE) will like to introduce the advanced technology of their seamless flux cored wire.
