>>> Hi-Frequency Welding SAW BLADE
Hi-Frequency Welding SAW BLADE Suits for the Cutting of Various Hard-Brittle Non-Metal Materials, for instance Granite, Marble, Ceramics, 
Concrete, Asphalt & Fire-Resistant Materials etc.
>>> Laser Welding SAW BLADE
Laser Welding SAW BLADE possesses the Merits of Strongly Welding Strength, Strong Capability of Hi-Heat Resistance. It specialty Suits for the 
Cutting of Asphalt, New and Hard Concrete, Granite and Marble etc.
>>> Currently in the Diamond Tools Industry, the Diamond Saw Blades mainly produced by Pressing, Hi-Frequency & Laser Welding. Hi-Frequency 
Welding is widely Adopted in Developing Countries, for Developed Countries Laser Welding is Prevailing now for the Consideration of Safety Issue. 
And this Tendency is Getting Obvious Time after Time nowadays.
>>> Hi-Frequency is Better than Laser Welding in the Following Points:
1, Lower Costs for Equipments;
2, Smaller Equipments so Easy to Move;
3, Simple Control and Easy to Mend;
4, Between the Substrate and Diamond Head there is Silver-Welding Piece acts as Filling-Materials, so it has not Strict Requests on the Radian 
of the Diamond Head;
5, Lower Price that can be Easily Accepted by the Clients.

>>> Laser Welding is Better than Hi-Frequency in the Following Points:
1, Bigger Equipments Needed;
2, Simple Control but Required of the High Regular Maintenance;
3, Normally it uses the Special Substrate (Hi-Frequency use 65Mn Steel, Laser use 30CrMo Steel);
4, Laser Welding does not have Filling-Materials between the Substrate and Diamond Head, meanwhile its Laser Diameter is Small. So it has 
Relatively Strict Requests to the Radian of the Diamond Head while Producing;
5, Due to Higher Costs in Diamond Head Producing, Equipments and Substrate Prices. Laser Welding Saw Blades mostly in Higher Prices;
6, The Laser Welding is in High Efficiency;
7, Its BIGGEST Merit is that During Dry-Cutting, the Laser-Welding Saw Blades DO NOT Exists of Teeth-Fallen Problem than other Craftworks.
